Status: REPORTED
Severity: normal
Priority: NOR
Component: kcm_kwin_virtualdesktops
Assignee: kwin-bugs-n...@kde.org

-- Information about the crash:
- What I was doing when the application crashed:
1. Open System settings and go to virtual desktops page
2. My setup is currently:
1st row: one desktop
2nd row: one desktop (interestingly, now both are named "2nd desktop")
3. Decrease row count below from two to one
4. Remove the bottom desktop with the trash icon
5. Click Apply -> crash
The reporter is unsure if this crash is reproducible.
