It's a bug in TestFlight causing a close on a duff file handle. This causes that crash.
Problem
I had a crash on an iPhone 4 with an exception type of EXC_GUARD. I can't find any information on this particular exception via google (only 1 result) or on stackoverflow. What is it? ``` Version: ??? (???)
