Missing proxy for identifier IBFilesOwner

Question

We've got an application that on rare occasions crashes with the error:

Missing proxy for identifier IBFilesOwner

We understand it to be implying that it can't find File's Owner for one of our nibs (xibs) but we've been through and confirmed they all have valid ones set.

There's practically zero on Google, can anyone offer any suggestions?

Thanks.

Hey I had the same problem and it turned out that I was doing some threading and I was executing code that should be on the main thread on another thread. I don't know what you're doing in your app, but hopefully that might give you a clue.

If you share some code we can try and figure out what's going on.
