Public bug reported:
Binary package hint: gdm
X restarts regularly when computer is idle.
This started to happen around 2009-01-28. I install all updates
available and do not change anything otherwise, thus it should be some
recent regression. Today was the first day I investigated it closer, and
it happened at 3:00:02, although I haven't found any cron task scheduled
for that time.

It can have something in common with the news user:
