Hi Peter, I do not think it is that easy to catch this with gdb.
You are starting a new session, so ksmserver is started. It crashes and so tdm brings you out and start anew.
I think you need to create a small monitoring script that monitors for ksmserver instances, then if so grab the pid
and attach gdb to it. You need to run this script from CLI before logging into TDE. Hopefully the script will be fast
enough to interrupt ksmserver before it crashes, then you can step through it, although it may be a long process
before you get to the point where it crashes.

IMO, the update of last friday broke something in your installation or in your current configuration.
1) have you tried creating a new user and logging into TDE as that user? Same crash?
2) if you run aptitude, do you see any broken dependency or errors?
3) did you update from one ubuntu version to another one or just updated "within" the same version?

Cheers
  Michele
