Looking at the stack trace, there was nothing that seemed to point to the
cause of the problem. I'm at work now but I'll post a trace over the
weekend. I use DebugKit from time to time, but it's usually off more often
than not. I'll run it through DebugKit and see what I can come up with. The
biggest mystery to me now is why did the error start "all of the sudden"
and why for some users and not others.
