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:
I get some Plasma crashes when I use my computer. It seems it happens mostly (exclusively) when a window is closed.

(Sorry to open a new ticket, selecting a bug report in the crash reporter and clicking the button saying I'm also experiencing it doen't do anything)

The crash can be reproduced sometimes.

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