Description Steven Roose 2015-11-24 15:57:23 UTC

Application: plasmashell (5.4.3)

Qt Version: 5.5.1
Operating System: Linux 4.2.6-200.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
- What I was doing when the application crashed:

I have Thunderbird open on one of my desktops. When I'm in a different desktop and click the Thunderbird icon (it's always in my taskbar), I move to the correct desktop and Thunderbird shows, but Plasma often crashes in the meantime.

- Unusual behavior I noticed:

Instead of just moving to the right desktop, the loader pointer (jumping icon next to pointer) also shows, as if the program is starting from scratch.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
