Description Neal Gompa 2015-10-25 06:49:43 UTC

Application: plasmashell (5.4.2)

Qt Version: 5.5.0
Operating System: Linux 4.2.3-200.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to move my panel arrangement back into place after rebooting after upgrading to Plasma 5.4.2. 

- Custom settings of the application:
Panels were set on each screen at the bottom, with the center one being the only one with the application menu and the systray. I also have wmsystemtray set up in the top right corner of my center screen for legacy applications.

The crash can be reproduced sometimes.

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