-- Information about the crash:
- What I was doing when the application crashed:
I was repeteadly hovering over taskbar entries. I already found which
duplicate this bug corresponds to, but the KDE reporting tool didn't find the
exact bug. I'm using the tool because I was able to get a backtrace. I'll be
marking this bug as a duplicate manually.
The crash can be reproduced every time.
-- Backtrace:
