Bug 361564

Application: krunner (5.6.1)

Qt Version: 5.5.1
Frameworks Version: 5.20.0
Operating System: Linux 4.5.0-3-default x86_64
Distribution: "openSUSE Tumbleweed (20160117) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Trying to reproduce this KWin bug:
https://bugs.kde.org/show_bug.cgi?id=361551
which caused this Plasma crash:
https://bugs.kde.org/show_bug.cgi?id=361563
Which prompted me to start Plasma again: alt-F2, type, boooom. Or perhaps plasma was still running and I tried to kquitapp it, not sure...

PS love the unobtrusive crash handling in the panel!

- Unusual behavior I noticed:
weird windowing issues, see https://cloud.josandcamila.com/index.php/s/Hbl07hLaUWriMrf

The crash can be reproduced sometimes.

-- Backtrace:
Application: krunner (krunner), signal: Segmentation fault
