KVO Crash #4
Description
Has anyone seen this crash? It's happening rarely but I'm trying to understand if it's in RequestQueue or client code. Line 124 is "isExecuting" and it's also occurring on 120 "isFinished". The queue is running requests with NSURLRequestReloadIgnoringLocalAndRemoteCacheData and a timeout of 120s
[RQOperation finish] in RequestQueue.m, line 124
Reason: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '<NSMallocBlock: 0x1d5e4ab0>: An -observeValueForKeyPath:ofObject:change:context: message was received but not handled. Key path: isExecuting Observed object: <RQOperation: 0x1e8aec40> Change: { kind = 1; new = 0; } Context: 0x0'
