Version:           unspecified (using KDE 4.6.0) 
OS:                Linux

We have an intermitent problem in kde4. 
When a user log in a kde4 segfault is issued. We attach the backtrace that it's showed, and only closing the application and log in again to the system works.
I can't reproduce the problem every time, sometimes it works and sometimes not and I can't trace why this is happening.
The user credentials are in a LDAP server and the user home is mounted by samba. 
Our distribution is OpenSuse 11.4 32bits.
