Bug ID: 439697
Summary: Gwenview crashes when rotating image during startup
Product: gwenview
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: gwenview-bugs-n...@kde.org
Reporter: k...@privat.broulik.de
Target Milestone: ---
SUMMARY
When rotating an image while Gwenview is busy during startup, it crashes. I
suspect it's the thumbnail generation code as it does not seem to happen when I
hid the preview pane.
STEPS TO REPRODUCE
1. Open a JPEG file in Gwenview
2. Quickly hit "rotate left"
OBSERVED RESULT
Often it crashes
EXPECTED RESULT
It does not crash
