Comment 2 Fedora Blocker Bugs Application 2021-02-27 06:29:12 UTC

Proposed as a Blocker for 34-beta by Fedora user krazyabouttechnology using the blocker tracking app because:

 Settings app is part of the core OS experience. Easily and consistently reproducible crashes should be considered a blocker.

Comment 3 Lukas Ruzicka 2021-03-01 11:58:45 UTC

I cannot reproduce it on my desktop running the same version, i.e. gnome-control-center-40~beta-3.fc34.x86_64. 
My default language input is Czech, I tried to add US English and Bengalese, both worked fine. Removing them was also flawless.
Which input sources have you tried? Maybe it is source specific?

Comment 4 Geoffrey Marr 2021-03-01 21:16:20 UTC

Discussed during the 2021-03-01 blocker review meeting: [0]

The decision to delay the classification of this as a blocker bug was made as we would likely vote to accept this if it was reproducible, but no-one in the meeting can reproduce it. We will ask the reporter to test with latest packages and try to get more info if they can still produce the crash.

Comment 5 Sumit Bhardwaj 2021-03-02 07:40:09 UTC

For me its still happening even with the latest updates etc. 

This is a Fedora 33 to 34 upgraded bare metal system using dnf system-upgrade. English (India) is my current language and I wanted to add a Hindi keyboard, but as soon as press the + button, it crashes with similar error in logs, so i think what language i am trying to add is not relevant as it does not reach to the language selection dialog even.

Is there any .config or .local directory that i can clear, which is used by the settings. If this is not happening for others it could be something specific to my system. Has anybody tried it on an upgraded system...clean iso or clean install is not having this issue, i also checked in a VM.

Comment 6 Sumit Bhardwaj 2021-03-03 10:44:06 UTC

Ok, i tried something. I ran the dconf reset command like below:

dconf reset -f /

It reset all my Gnome settings and i lost my customizations however it solved the problem. So I guess it was a bad configuration brought over from previous install. I am not sure if we can list it as a known issue or not but its definitely not a blocker it seems.

Comment 7 Sumit Bhardwaj 2021-03-03 10:48:45 UTC

Closing this as it seems to be specific to my system only and is resolved after resetting my Gnome configuration. But if its appearing on upgraded systems for others as well, then we might consider adding a known issue release note.

Comment 8 Viktor Ashirov 2021-03-31 10:54:05 UTC

Reopening, as it is still happening.

$ rpm -q gnome-control-center
gnome-control-center-40.0-6.fc34.x86_64

To reproduce, set this first:

$ gsettings set org.gnome.desktop.input-sources show-all-sources true

Then follow the steps from comment #0

Comment 9 Viktor Ashirov 2021-04-29 08:58:28 UTC

Changing the component as it was fixed after updating gnome-desktop3 to gnome-desktop3-40.0-3.fc34.x86_64

Fixed in https://koji.fedoraproject.org/koji/buildinfo?buildID=1739070
