Bug ID: 469554
Summary: Discover crashed when searching for updates
Classification: Applications
Product: Discover
Version: 5.27.4
Platform: Neon
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: discover
Assignee: plasma-b...@kde.org
Reporter: gabr...@lockebo.se
CC: aleix...@kde.org
Target Milestone: ---
Application: plasma-discover (5.27.4)
Qt Version: 5.15.9
Frameworks Version: 5.105.0
Operating System: Linux 5.19.0-41-generic x86_64
Windowing System: X11
Distribution: KDE neon 5.27
DrKonqi: 5.27.4 [KCrashBackend]
-- Information about the crash:
I clicked on the update notifier, which opened Discover normally. However,
before it finished searching for updates it crashed. Since it's got a backtrace
I thought it might be helpful to report, despite the lack of information. I
don't know what could have caused it.
I restarted Discover afterwards and could see that there was one Flatpak update
(OBS) as well as repository packages, two of which were from 3rd party repos
(Brave & 1Password). Not sure if this is related. Feel free to ask if you need
more details!
The reporter is unsure if this crash is reproducible.
-- Backtrace:
Application: Discover (plasma-discover), signal: Aborted
