Sorry, something along the lines of:

class MyAppDelegate(NibClassBuilder.AutoBaseClass):

   def init(self):

     import pdb;pdb.set_trace()
     self.foo = do_something()

So that I can track the creation of my application's main object and  
see where this disconnect that I'm experiencing is coming from.

When I tried that before and ran the built application by  
double-clicking on it, Console.app was filled with:

(Pdb) (Pdb) (Pdb) (Pdb) (Pdb) (Pdb) (Pdb) (Pdb) (Pdb) (Pdb) (Pdb) (Pdb)  
(Pdb) (Pdb) (Pdb) (Pdb) (Pdb) (Pdb) (Pdb) (Pdb) (Pdb) (Pdb) (Pdb) (Pdb)  
(Pdb) (Pdb) (Pdb) (Pdb) (Pdb) (Pdb) (Pdb) ...

   ad nauseum when that line was hit. There was no terminal I could  
attach to to take charge of the pdb session. Perhaps I need to run the  
application differently? (trying that) AHA!

Running:

   $  
~/Developer/ZopeEditManager/build/ZopeEditManager.app/Contents/MacOS/ 
ZopeEditManager

with the import pdb;pdb.set_trace() in my app's init() method brings me  
to a pdb prompt :)

Note to self: Don't use pdb and try to catch it through double-clicking  
the app :)

Good to know, thanks.
