Hmm, I guess it got stuck in horizontal tablet mode even though the screen is portrait. Some of the way it does this is a bit new in the current release version, so maybe I missed something that causes the problem!
Did you try switching tablet modes in the official release (not the debug one I linked here)? One of the fixes in that version is that it should specifically *not* crash when rotated, and reverting that fix is the change I made in the debug apk. If you choose 'phone' mode in the release apk I would expect the layout to rearrange to normal without crashing.
Either way, I'll try to fix this as soon as possible, of course it shouldn't be possible to even get in this state.
Edit: And thanks a lot for the photographs! It really helps a massive amount to get good debug info like that
