Bug ID: 436350
Summary: Plasma crash a few seconds after login following an
upgrade to Plasma 5.21.4
Product: plasmashell
Version: 5.21.4
Platform: Other
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: vaclav.ma...@atlas.cz
CC: plasma-b...@kde.org
Target Milestone: 1.0
SUMMARY
I upgraded to the latest Plasma version yesterday. Things worked fine at first
for a few hours, I played around a little bit browsing through the system
settings, maybe changing something here and there (nothing major). Turned off
the machine before bed. Started back up this morning and since then I've been
consistently running into the crash below about 10 - 15 seconds after an
otherwise seemingly successful Plasma start-up.
Starting up Plasma on the same machine while logged in as another (newly
created) user doesn't seem to be hitting the bug.
STEPS TO REPRODUCE
1. Log in
2. Do something for a few seconds
3. Crash follows
OBSERVED RESULT
Crash
EXPECTED RESULT
No crash
