X dies unexpectedly

[Gary Hodges]

This has happened twice since I installed Kubuntu 5.10.  I come in to
work and X has died over the weekend.  Both times were Saturdays, but
that I'm guess is coincidence.  The logs have the following repeated
several times (in the recent case 15 times):

And then the following occurs:

I'm guessing this is when X crashes as everything after looks like
normal junk.  Is this possibly a screensaver gone bad?
