After a few days of further analysis, based on the times of crashes I
don't think that this related to multiple sessions. It seems to be
more random than that and also happens when I've been logged onto the
system for several hours.

Thanks for the debug symbols. It turns out that WinDbg doesn't
necessarily make debugging this easier, but there is more of a
stacktrace now (assuming that this is the same crash, it doesn't
particularly look convincing to me, but I'm not too familiar with how
WinDbg formats stuff). I have been unable to actually save the crash
dump because WinDbg tries to open an explorer window during the save
process - which, of course, hangs since explorer is being debugged.

The best that I have been able to get so far is this module list which
I copied and pasted - I'll try to get some more information next time
this happens.

Sorry for the long message.
