Application: plasmashell (5.3.0)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-16-generic x86_64
Distribution: Ubuntu 15.04

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

After reboot i opened spotify and the plasmashell crashed. When i reboot after that and try to open other applications like firefox thunderbird i could work normal. When i start spotify client it directly crashes again.

The crash can be reproduced every time.

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