Description Tom Chiverton 2015-07-28 20:06:26 UTC 
Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.16.0-43-generic i686
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
Click cashew, change to other activity (I only have two)
Swap back.
Swap again, crash 90% of the time

- Unusual behavior I noticed:
configured swap activity global hot key (meta-tab, the default) doesn't work

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
