Public bug reported:
Kubuntu 9.10 AMD64 version, all packages updated.
Problem is simple:
1) X server has unexpectedly restarted.
2) Then GUI behaviour went wrong
3) Then system locked up when I attempted to re-login to desktop.
I managed to do emergency sync, so there is related part of kernel log
available:
