Comment 1 Jaime Torres 2015-05-06 19:05:55 UTC 
What I was doing before the crash:

Trying to save a file from chromium, kdialog started to use all cpu so I closed it.
After some time, plasmashell restarted with this crash.

Compiled from sources using version:
commit 98dffed888859f8fcdf9b078c6d093a174a0956f
Date:   Sat Mar 29 10:49:14 2014 +0100


Backtrace of the crash I experienced:

Application: Plasma (plasmashell), signal: Segmentation fault
