The difficulty is that this exception has never happened to me during development. By chance (maybe), it happened for 2 customers yesterday -- though it had been fine earlier in the day for one of them -- and when I sent them debug versions with NSBundle logging code the problem disappeared. Of course that made them happy ("fixed!"), but it didn't really get me anywhere.

I'm wondering, somewhat randomly, whether this is not something asynchronous, but perhaps something subtler like a missing write barrier. For example, if a separate process is involved in either loading the framework or loading the nib, and there's a missing write barrier for a value being returned to the app process, so that the processor caches were inconsistent, then it would only fail if the separate process happened to run in a different core and would only fail for a short while till the caches were consistent again. But this is beyond my competence, so it's probably just a fantasy.
