Comment 13 Jonathan Haas 2019-10-17 09:20:40 UTC 
Since a recent update of gnome-software, it crashes very often while running in background, often immediately after boot. This happens on multiple different systems by me. See also https://retrace.fedoraproject.org/faf/reports/2710719/

I haven't tested a clean install, but at the current state, this probably violates 
"There must be no [...] crash notifications [...] at first login after a default install of a release-blocking desktop."

Comment 15 Jonathan Haas 2019-10-17 10:06:54 UTC 
Actually, it looks like that commit fixes the issue, but it hasn't made it to Fedora 31, yet.
Comment 16 Kamil Páral 2019-10-17 10:35:48 UTC 
FWIW, I haven't seen this when operating just on RPMs. The traceback references flatpak, so I installed flathub repo into a clean F31 Workstation installation in VM, installed a few apps and rebooted several times, but I don't see any crash. It would be nice to figure out a more specific reproducer.
Comment 17 Jonathan Haas 2019-10-17 10:48:52 UTC 
I'll try to find a reproducer on a clean system, but FWIW, on one affected system I've installed a lot of Flatpak apps, so that might be related:

Looking at the list, this might be related to having the same application/runtime installed both system-wide and per-user.
Comment 19 Jonathan Haas 2019-10-17 14:43:24 UTC 
I couldn't reproduce that easily with just installing a flatpak in --user and --system. It likely has to do with having an update available or something like that, which I have no idea how to reproduce easily as you need to install old versions on purpose. Or can someone who understands this code better than me analyze https://gitlab.gnome.org/GNOME/gnome-software/blob/3e1fe203b40248f571be2a804027acd8e23dc54e/plugins/flatpak/gs-plugin-flatpak.c#L440 and post under which conditions the variable `flatpak` will be NULL in line 468?

Discussed at 2019-10-17 Fedora 31 go/no-go meeting, acting as a blocker review meeting: https://meetbot-raw.fedoraproject.org/fedora-meeting-1/2019-10-17/f31-final-go_no_go-meeting.2019-10-17-17.00.html . As we don't really have sufficient information on what causes this bug yet, we agreed to defer decision on blocker status until we have more information.

Comment 22 Jonathan Haas 2019-10-18 09:30:36 UTC 
The conditions for the crash are according to Will Thompson:

* at least one Flatpak has an available update
* at least one non-Flatpak GsApp (e.g. an RPM) has an available update
* the last GsApp in the list happens to not be a Flatpak – as far as I know this is non-deterministic.
Comment 23 Kalev Lember 2019-10-18 12:09:18 UTC 
I've backported the fix to gnome-software-3.34.1-6.fc31 (untested by me, but hopefully works).

Proposing as a FE as it's probably a good idea to pull this in through the freeze to avoid the updates process crashing.

I tried to reproduce this. On F31 VM, I installed ScummVM from Flathub using GNOME Software, and then downgraded it to an older version [1] using:

$ sudo flatpak update --commit=36c8229674e0180bf2137b58e14764a1493a5d671a95b6566ab772bba8d63c08 org.scummvm.ScummVM

Then I enabled updates-testing, which made a lot of RPM updates available. Rebooted, made GNOME Software recheck the updates, rebooted again and few more times still, but no crash occurred. Updated the RPMs, downgraded some of them, repeated the whole cycle, no crash. So unfortunately I can't verify the fix because I can't reproduce the error.

Comment 26 Adam Williamson 2019-10-18 17:01:01 UTC 
since we don't have any flatpaks installed in the live env or out of the box I'm not sure the FE case for this is super strong, but I think I'm a weak +1 FE just to make sure it's fixed for release if we test it and pull it in soon.
Comment 27 Jonathan Haas 2019-10-18 17:20:37 UTC 
I can't reproduce the issue anymore after installing that updated rpm. Before it happened very reliably shortly after every login.

Comment 29 Kevin Fenzi 2019-10-18 21:28:43 UTC 
+1 FE
Comment 30 Stephen Gallagher 2019-10-18 21:47:20 UTC 
I’m +1 FE for this.
Comment 31 Adam Williamson 2019-10-19 03:31:32 UTC 
That's +3 FE, so setting acceptedFE.
Comment 32 Stephen Gallagher 2019-10-21 12:50:15 UTC 
This was included in the RC 1.3 build and it appears to have fixed the issue for me and several others according to Bodhi, so I'd say that the blocker status of this is largely academic at this point.

That said, I'll vote -1 blocker on the grounds that while it's not a great user experience, it's also not actually impacting functionality and therefore would probably fail the "last blocker at Go/No-Go" test.
Comment 33 Adam Williamson 2019-10-21 15:51:25 UTC 
setting to VERIFIED per #c32 (and bodhi comments).
Comment 34 Fedora Update System 2019-10-21 18:54:17 UTC
