Description Jan Swaelens 2015-05-15 12:16:19 UTC 
Hello,

After updating my system last week (it looks like a major update since the desktop background and load screen changes as well) I am unable to access the desktop.

After logging on, the system produces an error (see provided back trace) and is almost completely frozen, but fails to perform anything really.




Reproducible: Always

Steps to Reproduce:
1. Logon

Actual Results:  
Obtained back trace:

Application: Plasma (plasmashell), signal: Segmentation fault
