Description Martin Tlustos 2015-07-28 10:26:17 UTC 
Application: plasmashell (5.3.1)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-23-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
Sometimes when clicking on the start menu, sometimes when opening an attachment from within kmail, etc. 

- Custom settings of the application:

I have several ppas enabled: kubuntu backports, an extra ppa for digikam and opencv and the ppa of our computer vendor, which also installs the intel xorg driver (which is a git version from 8th of July).

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".
