Application: plasmashell (5.3.2)

Qt Version: 5.4.2
Operating System: Linux 4.1.0-3-generic x86_64
Distribution: Ubuntu Wily Werewolf (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
IIRC I just dragged files (in dolphin) to folder in order to move them into that folder and plasma crashed.

I'm on Kubuntu 15.10 alpha 1 (wily), everything up to date.

-- Backtrace:
Application: Plazma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
