Crash Report (largely when saving)

[nocacounsel]

I wasn't sure whether to post a new thread for a crash report (versus adding to Scott's Crash Report thread), but here it is.

I find I sometimes get a crash report when doing a CTRL+S/Save and thus have to revert to one of the last autosaves (which is excellent such a feature is built into the game!).
As I can't give you the latest save I attempted to create, here is the last autosave file just prior to the crash and crash report I received when attempting to save.

Thanks!
