I am having a crash on Startup also.  It started after an update to KDE 3.5.7 release 10.1 which was followed by a power hit which caused the computer to restart. I am not certain which was the cause of the problem. Here is the trace:

System configuration startup check disabled.

Using host libthread_db library "/lib/libthread_db.so.1".
