Application: plasmashell (5.4.3)

Qt Version: 5.5.1
Operating System: Linux 4.5.0-1-amd64 x86_64
Distribution: Debian GNU/Linux testing (stretch)

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

Try to re-order the Favorite List of the Plasma "Application Launcher" with Drag & Drop

- Unusual behavior I noticed:

Plasma completely crashes.

Another thing that is odd in my configuration: I use two screens, and on my first screen, I always get re-set to "Layout: Desktop" after reboot / re-login, besides setting it to "Folder View". This is pretty annoying.

Maybe something when wrong when updating from KDE4 (debian stable) to KDE5 ...

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
