interesting. I am not a developer, but from the logs it seems like an OutOfMemoryError, not too uncommon on Android. I can't tell you which app/component is causing this, maybe someone from the project will chime in to help you.
Edit: you can also try a hard reset, maybe that will wipe some cache. To do that, hold all three buttons (power, volume up, volume down) for around 20 seconds until the device shuts off. It will then start by itself after a few seconds. The hard reset only simulates a battery disconnect.
