You were right on with number 1, the exception was in a line of code where I tried to use NSMutableArray +arrayWithArray on an NSData object rather than an NSArray. Fixed this blunder and everything works as it should.
I'm guessing what happened here is that some part of the +arrayWithArray method tried to call +count on the object given, which in this case was an NSData.
