Apple have sent me a crash log from an app sent for approval. Despite not crashing in all my tests in 3 devices, they say it is crashing on launch. After symbolicating the file, I get this.
Looking at this and means nothing to me. I don’t see where the error is. I know it crashed on thread 0, but which line?
Any clues? Thanks.

If you’re using Xcode 4, there’s a known issue with it not symbolicating crash logs correctly. See this question for a workaround.
