The other consistent thing that causes a crash and sometimes a crash dump is deleting history! That just happened to me a little while ago, I bloody well snapped. The thing that really pisses me off is that it happens to my autosaves aswell. They're supposed to be there for security, doesn't make me feel any better when Maya crashes and I open an autosave that should contain an entire car, which contains a headlight instead. I'm starting to consider switching to something else since all I do is modeling anyways. I'm sure one of the many free packages would work out much better.
