ImageIO: ERROR - MetadataLib.dylib not found

I'm getting an odd error in my console when ru开发者_开发问答nning my app sometimes:

ImageIO: ERROR - MetadataLib.dylib not found

I'm not sure what this is related to, but I am running AdMobs ads.

Yeah, so got a response back from Apple. Looks like it's a bug in 4.1's SDK that is addressed with 4.2's SDK. In my code, it was caused by a particular JPEG with a bunch of metadata in it. Upgrading to the latest SDK should eliminate the issue.
