Description Jakub 2015-12-23 10:09:26 UTC

Application: plasmashell (5.5.0)

Qt Version: 5.5.1
Operating System: Linux 4.2.6-301.fc23.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
Plasmashell was repeatedly crashing every time when I tried to browse for custom icon for new .desktop file. Sometimes it crashed as early as opening file context menu, or properties dialog, but it was rare.

Additionally I have 3 monitors setup with one panel and often have to kill plasmashell to make it adjust to screens. This setup doesn't seem to be very stable and may be tied to experienced problem.

The crash can be reproduced every time.

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