The stack trace is different but that's to be expected in cases like this. That upstream fix landed after version 40.0 so no it won't be included in gnome-desktop3 version 40.0-1. And no release of Ubuntu has any version newer than 3.38.5 yet.
** Also affects: gnome-desktop via https://gitlab.gnome.org/GNOME/gnome-desktop/-/issues/190 Importance: Unknown Status: Unknown ** Changed in: gnome-desktop3 (Ubuntu) Status: Incomplete => New ** Changed in: gnome-desktop3 (Ubuntu) Status: New => Fix Committed ** Tags added: fixed-in-40.2 fixed-upstream -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-desktop3 in Ubuntu. https://bugs.launchpad.net/bugs/1933022 Title: gnome control-center crashed with sigsegv in g_str_hash() whenever I try to add input sources Status in gnome-desktop: Unknown Status in gnome-desktop3 package in Ubuntu: Fix Committed Bug description: I've been facing the problems for about 9 months now. Back then I thought that maybe getting a new version would solve the problem, but turns out it didn't. Whenever I try to add some Input Sources from it just crashes. Reproducing it is very easy: running gnome-control-center, then going to Input Sources settings and clicking Add(+) would generate the crash. But the weird thing is that I've been unable to reproduce it in VM. And I also tried to reinstall most of the packages which, I think if changed/misconfigured would cause this but it didn't help. I also tried to use debsums to give some clues but didn't find any. After enough digging, this is what I can retrieve from gdb: #0 g_str_hash (v=0x506) at ../../../glib/ghash.c:2333 p = 0x506 <error: Cannot access memory at address 0x506> h = 5381 #1

3.24.29-1ubuntu1 i386 And this is not like that using the latest(not yet in main impish repo) pacakges and being in the Development Branch is causing the issue, as I already mentioned earlier. I just changed over to the Development branch for only 3 months now. I am also thinking of raising an issue on this on gnome GitLab. And for the time being, how can I get around this and add some Input Sources by, I don't know, changing some user configs?
