I can't seem to make it crash, but that said, I can't seem to get it to auto-rotate (auto-rotate setting is on "default"). I do however think that this is an issue with my phone though, as sometimes the auto-rotate feature is a bit flakey (I'm running LeeDroid and I botched something up a few weeks ago).
I think it must be your hardware or your Android build as we certainly dont' see that problem here on our various Android phones. I installed the App on my Samsung Galaxy Ace last night and its performing well on that phone too by the way too.
All the best
