10.8.1 & XCode 4.4.1 & NSUbiquitousKeyValueStore = CRASH

Guys,

I seriously think this is a new issue occuring after the update of 10.8.1 (MacBookPro Retina) with XCode 4.4.1

So here goes...

_ubiquity = [[NSFileManager defaultManager] URLForUbiquityContainerIdentifier:nil];

_defaults = [NSUserDefaults standardUserDefaults];

// if ubiquity is available - use it !

if (_ubiquity) {

_cloudStore = [NSUbiquitousKeyValueStore defaultStore];

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(storeDidChange:) name:NSUbiquitousKeyValueStoreDidChangeExternallyNotificationobject:_cloudStore ];

[_cloudStore synchronize];

.....

Later on in the code (someplace else)....

- (void) setDateOfBirth:(NSDate *)dateOfBirth

{

if (self.isCloudEnabled) {

[_cloudStore setObject:dateOfBirth forKey:@"dateOfBirth"];

} else {

[_defaults setObject:dateOfBirth forKey:@"dateOfBirth"];

[_defaults synchronize];

}

}

(_defaults is a NSUserDefaults object FYI - see above code seg)...

So when the line (_cloudStore setObject...) occurs, 4 seconds later i receive a crash....

Per debugger in xcode...

libxpc.dylib`xpc_get_type:
0x373dc10c: ldr r0, [r0, #4]
0x373dc10e: bx lr

With the iPhone connected (disconnected from the machine), the error occurs again, and the crashlog shows the following... Key thing to notice is that the crash occurs in libxpc.
