Description Adam Williamson 2023-08-15 18:23:16 UTC 
openQA is showing that plasmashell sometimes crashes when we open the "Status and Notifications" pane and click "Notifications", e.g. here:

https://openqa.fedoraproject.org/tests/2073354

if you watch the video - https://openqa.fedoraproject.org/tests/2073354/video?filename=video.ogv&t=51.08,51.12 carefully, around the 11:30:36 mark, you can see the test clicks Notifications, and the entire desktop briefly goes black while the shell reloads. In the system logs we see this:

(the timestamp difference is just a timezone thing). Not sure how to get better details on the crash, please advise.

Reproducible: Sometimes

Steps to Reproduce:
1. Boot a Fedora 39 or Rawhide KDE live image
2. Wait ten minutes (probably not necessary, but openQA does this)
3. Click the up-arrow thingy in the bottom right pane to open the "Status and Notifications" pane
4. Click "Notifications"
Actual Results:  
Desktop briefly goes black then reloads, you never actually get where clicking "Notifications" should have taken you

Expected Results:  
Clicking "Notifications" should work as expected
Comment 1 Fedora Release Engineering 2023-08-16 08:08:14 UTC 
This bug appears to have been reported against 'rawhide' during the Fedora Linux 39 development cycle.
Changing version to 39.
