No, that's unnecessarily detailed, but certainly not wrong.

The crash looks weird.  It looks like your machine doesn't return
the machine sid when it's requested.  Can you please run the following
test application as non-admin and as admin and paster the output for
both cases into your reply?  Hmm, maybe that's a windows XP thingy?
I didn't test this stuff on anything prior to Vista.
