Bug ID: 489702
Summary: Plasmashell crashes when clearing clipboard
Classification: Plasma
Product: plasmashell
Version: master
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Clipboard
Assignee: plasma-b...@kde.org
Reporter: akse...@akselmo.dev
Target Milestone: 1.0
SUMMARY
When clicking on the clean clipboard history button, plasmashell crashes.
I am not sure why but I think it has something to do with having clipboard
history, then rebuilding plasmashell (or just restarting PC) and then trying to
clear it.
STEPS TO REPRODUCE
1. Add a lot of text and images (like with spectacle) to your clipboard
2. Restart PC and/or rebuild plasma dev session
3. Log in and try to clean clipboard
OBSERVED RESULT
Plasmashell goes crash
EXPECTED RESULT
No crash!
