Description Adam Williamson 2020-10-16 17:30:17 UTC 
This is kind of a follow-on from https://bugzilla.redhat.com/show_bug.cgi?id=1887969 . We fixed *that* crash, but metacity is now crashing a bit later in startup:

Stack trace of thread 1825:
#0  0x00007f4bc77a0975 raise (libc.so.6 + 0x3d975)

#14 0x00005578b8f7885e _start (metacity + 0x1385e)

and this still prevents the installer from working at all. I'm working on getting a full backtrace, but just from that one it looks like we're crashing in the code changed in this commit:

Comment 2 Alberts Muktupāvels 2020-10-17 17:49:45 UTC 
Can you check if https://gitlab.gnome.org/GNOME/metacity/-/merge_requests/16 fixes crash?
Comment 3 Martin Pitt 2020-10-19 13:20:43 UTC 
@Alberts: I did check it now (took a while, had to learn how), and it does *not* fix it yet. See upstream PR for details.
Comment 4 Jan Kaluža 2020-10-21 05:56:36 UTC 
I can also reproduce it in Fedora ELN (which is based on the same metacity/anaconda version it seems).
Comment 5 Adam Williamson 2020-10-21 06:18:03 UTC 
We're mostly discussing this on the upstream MR, FWIW. It's proving a bit recalcitrant. https://gitlab.gnome.org/GNOME/metacity/-/merge_requests/16#note_939936
Comment 6 Adam Williamson 2020-10-21 16:38:48 UTC 
So this turns out to be a bug in libXres. halfline found it and sent a fix, I tested it:

https://gitlab.freedesktop.org/xorg/lib/libxres/-/merge_requests/1

I'll backport it in an official build in a couple hours, I have to run out first.
Comment 7 Adam Williamson 2020-10-21 21:31:52 UTC 
https://koji.fedoraproject.org/koji/buildinfo?buildID=1628561 fixes this, I just tested. Will be in next Rawhide compose. Thanks Ray for the fix.
Comment 8 Adam Williamson 2020-10-21 21:33:20 UTC 
Oh, for the record - that fixes it with no change in metacity necessary. Fixing metacity to handle XResQueryClientIds failing is still a good idea, but not necessary to fix this bug.
