Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: discover
Assignee: [email protected]

Target Milestone: ---
Application: plasma-discover (5.24.4)
Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 5.15.0-27-generic x86_64
Windowing System: X11
Distribution: Ubuntu 22.04 LTS
DrKonqi: 5.24.4 [KCrashBackend]
-- Information about the crash:
- What I was doing when the application crashed:
I was connected to the desktop session running XRDP, via KRDC client.
I opened up Discover, and it said it was fetching updates. I clicked around a
bit in the GUI, as it seemed no updates were coming, and it crashed. I've seen
it do this before, seemingly misbehave over RDP.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
