So yeah, I finally found a way to reproduce it in any system up until version 40.0-1. Here's how:
1. Using gsettings or dconf editor, changing the /org/gnome/desktop /input-sources/show-all-sources key to true which is in org.gnome.desktop.input-sources schema and then going on to add(+) a new source causes the crash. 2. Alternatively using gui: installing gnome tweaks and then enabling "Show Extended Input Sources" from "Keyboard and Mouse" can generate the same segfault crash. But the good thing is that as you said, there is a fix upstream and apparently it's landed in version 40.1-1 as I've tested it in Fedora 34 vm I've found it working properly. So waiting to find the updated packages in impish-proposed and sorry! there was a miscommunication about the version number. I thought the fix had landed in 40.0-1 but rather it was the version the bug was found. And I have Pre-released updates turned on. -- 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.

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?
