Comment 1 Riccardo Iaconelli 2008-12-21 12:54:02 UTC 
can you reproduce it every time or it has just been an episode?
if you can reproduce it regularly, can you tell us something more about steps to reproduce it?

Hi Riccardo,

I am sorry, I am not able to reproduce it. I will add info here if I find a way to do so. All I can say right now is that it happened shortly after login, but I guess this does not help much...
Comment 3 Dario Andres 2009-03-25 23:32:33 UTC 
This may be related to bug 182010 / bug 180625
Have you experienced this crash again with a recent KDE and an updated Qt ?
Thanks
Comment 4 Marc Schiffbauer 2009-03-26 00:09:32 UTC 
No this has not happened to me with qt4.5/kde4.2.1 here.
Comment 5 Dario Andres 2009-03-26 00:11:29 UTC 
I'm glad it works now. Marking as WORKSFORME. Reopen if you experience the same crash again. Thanks
