Comment 1 K900 2011-10-11 06:57:02 UTC 
Can be reproduced both on my setup and on a clean system (in VirtualBox or with mv ~/.kde ~/.kde_test)
Comment 2 K900 2011-10-11 09:31:13 UTC 
Tested again with 0.8.80. Strangely it works now. The latest git still crashes.
Comment 3 Lamarque V. Souza 2011-10-11 17:18:32 UTC 
I am not able to reproduce this problem. 0.8.80 and latest git are almost the same, this look like a intermitent problem.
Comment 4 K900 2011-10-11 17:25:47 UTC 
Hmmm... I'll try to get somemore info with gdb and see why it crashes.
Comment 5 K900 2011-10-12 06:55:42 UTC 
Strange, doesn't segfault anymore. OK, setting as worksforme.
