Sentry Crash Report:

Description Aleksi Uotila 2015-08-06 07:18:39 UTC 
Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-25-generic x86_64
Distribution: Ubuntu 15.04

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

Started the OS. Then logged in to KDE. Plasma shell crashed during startup process.

(This may not be related but during the normal use of the system I'm also experiencing freezes in plasma desktop. Applications remain responsive in these freezes but plasma desktop, alt+f2 app starter, application launcher, all the desktop panels are frozed ie. not responsive. After some seconds 10-15 they becore responsive again and execute all the button presses done during freezing e.g. apps get shown and hidden if their icons were pressed on the bar during the freeze.)

The crash can be reproduced every time.

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