title: UIWebView EXC_BAD_ACCESS crash
body: <p>I'm experiencing crashes of an app that uses UIWebView. Usually it's when page is not fully loaded and UIWebView is sent stopLoading selector. Or when UIWebView fully loaded page. I've got <code>EXC_BAD_ACCESS</code>. Stack looks like this:</p>
  
  <pre><code>#0  0x95bb7688 in objc_msgSend
  #1  0x30a671db in -[UIWebView webView:decidePolicyForNavigationAction:request:frame:decisionListener:]
  #2  0x3024a10d in __invoking___
  #3  0x30249ff8 in -[NSInvocation invoke]
  #4  0x358ab160 in HandleDelegateSource
  #5  0x302452c1 in CFRunLoopRunSpecific
  #6  0x30244628 in CFRunLoopRunInMode
  #7  0x32044c31 in GSEventRunModal
  #8  0x32044cf6 in GSEventRun
  #9  0x309021ee in UIApplicationMain
  #10 0x0000239c in main at main.m:13
  </code></pre>
  
  <p>for me most strange thing here is <code>webView:decidePolicyForNavigationAction:request:frame:decisionListener:</code> selector sent to UIWebView, because there is no such selector in UIWebView documentation! Only for Cocoa (not cocoa touch) WebView.
  I suspect that there is something wrong with UIWebView or its delegate. But I can't set breakpoint to watch them. Please advise how I can get more info in this situation.</p>
