iPhone 4.0 SDK UIWebView crashes with DOMHTMLElement error

My app have an UIWebView and I open a twitter oauth page with it.

when I open oauth page , it works well.

after I sign-in, it redirects to another page which have PIN code.

and It crashes down with logs below.

Is it a bug in 4.0 SDK?

I've got it. This might have been a problem with auto generating link.

Turn off all detection of your UIWebView.

In my case, detection of phone numbers was issues.

Deactivating detection of links did it for me in the UIWebView! I tried phone numbers first and that wasn't enough. Very strange.

I had exactly the same problem and, in my case, deactivating the phone number ditation did work.

webView.dataDetectorTypes = UIDataDetectorTypeLink;

Very strange issue.
