Unrecognized selector crash

[tonyarnold]

I'm hitting a crash in TICDSDocumentSyncManager.m:

- (void)vacuumOperation:(TICDSVacuumOperation *)anOperation failedToCompleteWithError:(NSError *)anError
{
    TICDSLog(TICDSLogVerbosityErrorsOnly, @"Vacuum Operation Failed to Complete with Error: %@", anError);
    [self ti_alertDelegateWithSelector:@selector(documentSyncManager:didFailToVacuumUnneededRemoteFilesWithError:), anError];
    [self postDecreaseActivityNotification];
}

Specifically the line calling TICDSLog(). The error passed through is an instance of NSError, but calling po on the object in LLDB returns:

Printing description of anError:
(NSError *) anError = 0x0bac0780
2012-07-24 23:12:25.325 AwesomeClientApp[5427:c07] +[TICDSFileManagerBasedVacuumOperation localizedDescription]: unrecognized selector sent to class 0x30a0b4

Could you get me a bit more information on this one? If you enable TICDS logging by including a call to [TICDSLog setVerbosity:TICDSLogVerbosityEveryStep]; somewhere near application launch it will log everything the framework does. Just include a partial dump of that output near where the error occurs and that should help me track down where it's coming from.

Thanks Tony, that looks to be enough info to give me a good starting point for figuring out what's wrong.

No worries — just let me know if you need more info.

Tony,

I'm not able to trace this through the code. Could you possibly email me a sample project that does this or give me instructions to reproduce it?

best, Michael
