Rare java.lang.StackOverflowError crash in AdMob 6.4.1 for Android

[I.D.E.]

I'm seeing a very rare crash in AdMob, when an ad is loaded from an XML layout file. This was shown in my ACRA reports:

Note that it's very rare in the number of occurrences. I'm just letting people know.

All the AdMob code is doing in this trace is initializing a new WebView. I don't think AdMob is the root cause here. Is your app doing any kind of recursion with AdMob banner calls?

Thanks,
