2009-11-09 11:04:50.605 Wish[71694:10b] .
/usr/local/bin/wish: line 2: 71694 Segmentation fault      "$(dirname 
$0)/../../../Library/Frameworks/Tk.framework/Versions/8.5/Resources/Wish.app/Contents/MacOS/Wish"

It's the call to Tk_MainWindow that's causing the crash. What's weird is 
that Wish also crashes when I simply run the standard NULL check:

   if (Tk_MainWindow(ip) == NULL) {
     return TCL_ERROR;
   }

No error, just a hard crash. If the root toplevel is mapped (.), 
shouldn't it not do this?

I didn't get to the refCount yet.
