[Bug 662188] [NEW] Ubuntu 10.04 crashed while attempting to switch user

[Nur Sah]

Public bug reported:

While I was trying to switch from one user to another in ubuntu 10.04
the system gave me a black screen and crashed. I had to restart the
computer.

Unfortunately I can't repeat the same problem to verify it, it has
happened during an exam, however I got the syslog and Xorg.0.log files
so I would be able to check them.

here are the lines that I thing you might have a clue.
