Can you reproduce this crash? If not we have a problem because your backtrace regrettably is completely useless... (see http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports on how to get useful backtraces) However, it looks as if you stumbled upon bug #169147. Do you have an nvidia card and are using the closed-source drivers?
I have the same problem. KWin either freezes or crashes on every logon.

And yes, after it is restarted, it works normally from that point.
All right I missed to write some further information in my bug report. This is my machine and yes, I am using the closed-source nvidia driver. I also use some 3-D desktop effects. If a list of active effects is helpful I will generate a list. Here the info to my machine: Qt: 4.4.3 KDE: 4.1.2 KWin: 3.0 Kubuntu: 8.10 nvidia driver 177.80 @ Oliver Putz Thanks for the Link to the "Development/Tutorials/Debugging/How to create useful crash reports". I will read it through and try to create a useful crash report. By the way the error occurs now on every KDE long-in.
I found that this only happens when the Blur effect is turned on. If I turn it off, KDE boots normally. Tested on 2 PCs, both Kubuntu 8.10 with nvidia 177.80.
If Sahin's is also due to the blur effect then this is a duplicate of bug 164889.
No response, assuming duplicate. *** This bug has been marked as a duplicate of bug 164889 ***
