Bug 347126

Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-15-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
logging in. I have 2 amd machines this has happen to currently working on removing plasma-desktop and kubuntu-desktop then purge both to reinstall to see if that fixes the problem. I really hope it does the last Live session i did failed to install Both machines where upgraded from 14.10 and now not useable if the reinstall does not work ill have to do a clean install but it will be back to 14.04LTS

The crash can be reproduced every time.

-- Backtrace:
