Description Laurent 2017-01-11 19:30:38 UTC 
Application: plasmashell (5.8.3)
 (Compiled from sources)
Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.36-8-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed:
I moved the mouse on the launcher application, unrolled the "development" menu then a "development" sub-menu and place the mouse on one of the sub-menu items, and then I move the mouse on the menu " Recent Applications ". That's when "KDE" crashed.

The crash can be reproduced every time.

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