NSURLConnection crash on POST

[Mark Christian]

The NSURLConnection is implicit -- I send my NSURLRequest to a  
WebFrame, and some time later, the NSURLConnection error pops up. I  
never set the delegate myself.

Right now, the NSURLRequest is an autoreleased object. However, if I  
change it to an alloc/init retained object, I still get the crash.

Also, and frustratingly, this exact code used to work. The only  
difference is that the WebFrame is now pointing to a page with a  
frameset, whereas it wasn't before.

Where else can I look for release bugs?
