Game crash apparently at autosave

[GC13]

Well this is interesting. At first I thought this problem was due to my new graphics card drivers, but rolling them back to the previous version didn't help. It doesn't even seem to necessarily be at the autosave: I changed the autosave timer with the preferences file to 1000 rather than 10, and it still crashed about ten minutes in (except it wasn't auto-saving). The funny thing is, if this debug report is accurate, it successfully autosaved before crashing me (which it must have, as it went for a good while and I had changed the autosave timer back after rolling back my drivers).

Anyway, here's the debug report. Has anyone seen this before? I've seen all sorts of stuff about the game crashing at autosave, but nothing helpful. I'm recording with D3DGear, as I have done successfully twice.

[Gondlar]

Bug reports should go to the Mantis bug tracker.
I've run a few keywords through it's search. Your issue sounds like Bug 2688. It does not have a solution yet though.

[GC13]

I don't think they're the same issue, as mine doesn't force a restart. It just freezes the program (and Windows will ping every time I try to issue a command to the program), until I ALT-F4 it.

And this isn't a bug report, this is troubleshooting.

[Gondlar]

You said you were recording your screen iirc. Does it work without recording?

[GC13]

I haven't tried it without recording today, but I've recorded two videos just fine.

Since rolling back the drivers didn't fix the problem, the only other changes I've made have been installing Legend of Grimrock and Hard Reset on Steam. Normally I wouldn't mention that, except I'll never forget the time that uninstalling Space Siege's GPGNet kept me from being able to play Alpha Protocol.
