Hi,

I hit this error when using WebKit with garbage collection on, "malloc: * auto malloc[731]: error: GC operation on unregistered thread. Thread registered implicitly. Break on auto_zone_thread_registration_error() to debug." 

And when I turned off garbage collection, the error did go way!

My app works like this , when users double click a row in my NSTableView, it will get a URL from that row, then ask WebView to load the page from that URL:

//code snippet

   [tableView setDoubleAction:@selector(doubleClickAction:)]; 
    ...

   - (IBAction)doubleClickAction:(id)sender { 
       ...
       /* cause that malloc error */
      [[webView mainFrame] loadRequest: [NSURLRequest requestWithURL: row.url]];   
   } 

When the error happens, the app does not crash, it continues to work. Actually It seems no harm at all. 

I am not sure if this is a bug or I just did not use the webkit api in a correct way. 

Thanks!
