Bug ID: 453987
Summary: Okular crash when canceling more actions than done
Product: okular
Version: 22.04.1
Platform: Neon Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: okular-de...@kde.org
Reporter: pasdabonneme...@gmail.com
Target Milestone: ---
Application: okular (22.04.1)
Qt Version: 5.15.3
Frameworks Version: 5.93.0
Operating System: Linux 5.13.0-41-generic x86_64
Windowing System: X11
Distribution: KDE neon User - 5.24
DrKonqi: 5.24.5 [KCrashBackend]
-- Information about the crash:
- What I was doing when the application crashed:
I opened a pdf, added a note without writing on it. Then I right clicked on it
and "cancel (Ctrl+z)".
It crashes immediately because there is nothing in the note to cancel.
- Unusual behavior I noticed:
The cancel option is available when there is nothing to cancel.
- Expected behavior:
I was trying to remove the Note. There is no cancel button on it, and by
right-clicking the cancel option is available (and no remove Note option). So I
thought it might remove the note. But it just make the app crash.
The crash can be reproduced every time.
-- Backtrace:
Application: Okular (okular), signal: Segmentation fault
