I've seen crashes like this (did not take snapshots of the traces to compare) as well. If I remember correctly, the built-in Map app can be crashed like that, too. Just as your trace shows, this occurs mostly in animateTo(). I suspected this had to do with memory availability (or lack thereof) when new tiles are loaded, so I spent a few days on optimizing memory usage on my end. I found the problem tapered off considerably after that campaign. When testing, I have to try pretty hard now to trigger this (on a standard G1 or emulator session).
