Sentry Crash Report:

Description Niko Wenselowski 2014-10-01 21:04:11 UTC 
Starting an application results in a crash of plasmashell.
This happend to me with applications started via the K-menu and via ALT+F2 (kickoff?) but I was not yet able to somehow trigger this behaviour.
The start of the application itself is not affected in any way.

Packages are the current nightlies from Launchpad - ppa:neon/kf5

Reproducible: Sometimes

Steps to Reproduce:
1. Open K-Menu
2. Click on an application to start it

Actual Results:  
Plasmashell crashes

Expected Results:  
Plasmashell continues to work.

Application: plasmashell ()

Qt Version: 5.3.2
Operating System: Linux 3.13.0-36-generic x86_64
Distribution: Ubuntu 14.04.1 LTS

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