This has been bugging me for ages but I've finally been bothered to run logcat after a crash. Unfortunately this is really hard to reproduce - simply pausing QD and disconnecting/reconnecting WiFi doesn't cause it. It seems to only occur after QD has been backgrounded for a long time.
I don't know enough about Android dev to figure things out much beyond that and, despite now having a stack trace to see where the unhandled exception is being thrown from, I'm not sure what the best solution would be, so hopefully someone smarter than me can get this sorted!
If it helps, I'm running Android 4.1.2 (custom ROM, Release 30) and the latest committed code of QuasselDroid.
Here's the relevant dump from logcat:

If I figure out a way of fixing this myself in my fork, I'll submit a pull request, but don't hold your breath :-p
