Sentry Crash Report:

Description David Leal 2015-05-25 13:13:18 UTC 
Application: plasmashell (5.3.0)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-18-generic i686
Distribution: Ubuntu 15.04

-- Information about the crash:
I can't reproduce this all the time, initially, but after a certain time it happens all the time: the only thing I need to do is to switch to a different buffer (using C-x b), wait a second or 2, and the crash popup appears. I'm using xmonad instead of kwin, not sure if that makes a difference. I'm not sure what more information may be useful, but I'll be happy to provide more

The crash can be reproduced every time.

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