Application: plasmashell (5.2.95)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-15-generic x86_64
Distribution: Ubuntu 15.04

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

Press Meta+Q to show activity bar (at first time activity bar was shown)
Close activity bar
Again press Meta+Q to show activity bar -> plasmashell always crash when show bar for second time

The crash can be reproduced every time.

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