IPhone app crashes unpredictably (iAd related?)

Question

Here's the top of the crash log that gets generated. Always the same.
Looks like iAds is always the culprit.
Is it my code, some anomaly with iAds, or what?
Thanks for any input.

Answer 1

I don't have the problem, but I have seen messages that say that a restart usually fixes it, and if that doesn't clear cookies, history and cache in settings/Safari and then restart again. If this also fails try to Reset Network Settings, also in settings.
