Comment 6 Chris Murphy 2020-11-02 06:25:43 UTC 
Crash happened with PackageKit-1.2.1-1.fc33.x86_64
Comment 7 AsciiWolf 2020-11-03 19:12:27 UTC 
Same issue on Fedora 33 with PackageKit-1.2.1-1.fc33.x86_64.

Also, this was in journal log:
packagekitd[1666]: g_dbus_proxy_call_sync_internal: assertion 'G_IS_DBUS_PROXY (proxy)' failed
Comment 8 AsciiWolf 2020-11-03 19:14:24 UTC 
It happens every time after I log in.

I have tried to report this issue with GNOME ABRT GUI, but it did not get reported.

PackageKit-1.2.2-1.fc33.x86_64 in update-testing crashes.
Comment 13 Daniel Rusek 2020-11-05 12:07:01 UTC 
This upstream PR should fixed the crash: https://github.com/hughsie/PackageKit/pull/437

However, it was not included in the latest build for some reason.

PR and scratch build with the pat, if that helps:

https://src.fedoraproject.org/rpms/PackageKit/pull-request/6
https://koji.fedoraproject.org/koji/taskinfo?taskID=55239989

(I have yet to test it).
Comment 15 Daniel Rusek 2020-11-09 15:00:09 UTC 
Any chance you could do a F33 build? I don't have any Rawhide machine here at the moment and the F34 build has broken dependencies on my F33 machine.

COPR build for testing https://copr.fedorainfracloud.org/coprs/atim/PackageKit/
Comment 17 Daniel Rusek 2020-11-09 15:37:01 UTC 
Thanks! I can confirm that after installing the COPR build, PackageKit no longer crashes on my machine.

Comment 26 Daniel Rusek 2020-11-11 16:06:07 UTC 
I am reopening this issue since the fix apparently caused another regression (see bz#1896540) and was unpushed from stable on F33.
Comment 27 Daniel Rusek 2020-11-12 14:18:07 UTC 
I really hope that this issue will get fixed properly since it apparently causes PackageKit to crash during every boot on all Fedora 33 Workstation installations.
Comment 28 Adam Williamson 2020-11-12 17:29:48 UTC 
It certainly doesn't do that, because it never made it out of updates-testing.
Comment 29 Daniel Rusek 2020-11-12 18:20:56 UTC 
Sorry, but that is not correct. I have tested this on multiple Fedora 33 Workstation systems (that certainly do not have) updates-testing enabled and have segfault in dmesg + ABRT report on *every* of them.

They all have PackageKit-1.2.1-1.fc33.x86_64 that was pushed to stable two months ago: https://bodhi.fedoraproject.org/updates/FEDORA-2020-9813075759

Comment 30 Daniel Rusek 2020-11-12 18:23:05 UTC 
Sorry for the typos in previous comment. Also, I forgot to mention that some of the F33 systems were newly installed and fully updated VMs.
Comment 31 Adam Williamson 2020-11-12 18:28:58 UTC 
Oh, sorry, I was thinking about the follow-up bug, not the initial problem.

Comment 35 Ladar Levison 2020-11-13 19:32:59 UTC 
Similar problem has been detected:

I connected to the guest virtual machine using "remote-viewer spice://127.0.0.1:5901" from a CentOS 8 host 
machine. I enabled the second display, up popped the window. I clicked full screen on virtual display 2, and 
it went full screen. The virtual display resized accordingly. Then I hit full screen on virtual display 1, and that's 
when the spice connection crashed. I was able to log into the guest via SSH, but couldn't get access to the console 
without rebooting. The only clue I found was in the log, and of course the packagekit crashes associated with this
bug report. I repeated the process several times. 

In case it isn't obvious, I have the guest setup with a QXL graphics device, with 2 heads.

If problem still persists, please make note of it in this bug report.
Comment 47 Ladar Levison 2020-11-24 00:51:55 UTC 
In my case this bug was a byproduct of a more serious issues. Namely, the display server/console was crashing. The system would be accessible via SSH, but the console become non-responsive. I never got an abrt report regarding the display server crash, just this packagekit crash (after rebooting). 

In this case Fedora 33 was running as a virtual guest, and I was triggering the bug by adding a second "head" to the QXL configuration. I could connect to both displays just fine. But when I tried to switch both virtual displays to full screen, the display server would crash. As it turns out, my monitors (1920x1200), were just a little bit too big for the default 16 mb QXL display buffer. I think two 1080p screens will barely fit within 16mib which might be why this hasn't bother more people. After significant pain, I discovered that increasing the QXL memory allotment to 32mib seems to have fixed the problem. 

It took several hours to figure this out, so I want to report it for the benefit of others, but I'm not sure where to report it. 

In a perfect world, that the display server shouldn't crash/lockup to begin at all. It's worth noting that I managed to avoid the crashed by adding "qxl.num_heads=2 qxl.modesetting=1" to the kernel params (by default the guest driver sets up 4 heads), and then logging in using the Xorg display server (instead of Wayland). This seemed to avert the crashes. (Wayland would still crash.) Unfortunately, this wasn't a fix, but was certainly support superior, as resizing the second monitor to 1920x1200  would succeed, while silently reducing the resolution. This happened with both the Gnome control panel and with xrandr. It took awhile, but I finally realized that was happening because the system couldn't expand the virtual screen to 3840x1200. Why this prevented the crashing, I don't know. And of course, the system should told me this was a problem because the QXL memory buffer was too small.

Perhaps this comment can get added to virt-viewer, and in the future it will automatically resize the QXL buffer when it detects that the default 16 mib is insufficient for the current host monitors.
