The backtrace is unfortunately useless, please see http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports .
I cannot get a decent backtrace either, although the build is debug-enabled. Yet it happens with the latest kde4:factory packages for 10.3 too. What I get is: [New Thread 0xb57ee6f0 (LWP 8356)] Qt: gdb: -nograb added to command-line options.

I got it working again. It's the nvidia binary driver. While 173.14.12 breaks it, 177.13 (beta) works. Before I installed the 177 some days ago I ran the version before 173.14.12 without problems, I think it was 173.14.09. So either it is a nvidia bug, or there were changes on both sides that lead to the crash. Reverting kwin to revision 836665 does not solve the issue.
It seems I had some left-overs from the 177 manual install when updating the kernel driver packages. After running the uninstall for the binary driver again and refreshing the packages from nvidia, it all works now. Have you installed the drivers manually before?
confirmed beta drivers eliminate the crash on startup, although system stability is compromised.
Driver problem then.
