I just had a beta tester contact me about a very similar error/crash. It's slightly different than I've seen before, but it certainly seems related.
The tester was closing a window backed by NSDocument. In response the AppKit document machinery was attempting to create an NSSavePanel, to allow the user to save or discard the file, but NSRemoteView threw an exception[1]. As I mentioned earlier in this thread, I've come to anticipate this. I now wrap the relevant NSDocument method to catch any exceptions and display a warning alert that the system save panel is (apparently) temporarily unavailable. This time the app crashed while trying to generate that alert; -[NSAlert init] was loading some localized string and crashed[2]. I doubt this is going to be reproducible, but it's reported as rdar://21881669. ~Martin Wierschin [1] INITIAL EXCEPTION: MyApp[807]: *** Assertion failure in -[NSRemoteView setServiceObject:forKey:], /SourceCache/ViewBridge/ViewBridge-105/NSRemoteView.m:3142 failed: <NSRemoteView:> invalid in: NSInternalInconsistencyException line 0 STACK TRACE: ... libobjc.A.dylib objc_exception_throw CoreFoundation +[NSException raise:format:arguments:] Foundation -[NSAssertionHandler handleFailureInMethod:object:file:lineNumber:description:] ViewBridge -[NSRemoteViewBase setServiceObject:forKey:] Foundation NSKeyValueNotifyObserver Foundation NSKeyValueDidChange Foundation -[NSObject(NSKeyValueObserverNotification) didChangeValueForKey:] AppKit -[NSDocument _preparedSavePanelForOperation:] ...
