This had not been a problem elsewhere, but I can see why it does not work with py2app.  So, I'll make sure to avoid a name collision between my init module and all packages, which sounds like a good practice to follow anyway.

The follow process creates a failing AppKit import from the app bundle for me and shows different sys.path for 'python quot.py' vs app bundle launch.  I can provide much more detail (including modulegraph debug output) if requested, but the following steps in a Terminal window can reproduce the error for me every time.

This is on OSX 10.6.8, using the system version of Python 2.6.1.  The 
only non-standard packages/modules are py2app (0.6.4 pre-release and its 
requirements) installed local to the user account.  I am developing as 
vanilla as I can get.
