Unfortunately this happens a lot of time on some devices, when the application is paused/resumed. We weren't able to reproduce the issue on our own devices, but our crash reporter logged this one (or a variant) quite a lot. We probably can send a Pull Request since this is a trivial fix. 3164 1 sgothel 2013-10-23 16:58:53 +0200 Add missing 'else' in branch Thank you!
