I was able to reproduce the issue on my Lion system (running Python 
2.7.3, linked to system Tk 8.5.9).

Since I saw no issues with your code, and I don't see these issues in my 
own, similarly-built Tkinter apps (wrapped with py2app), I looked to see 
where our setups differed. The only thing I noticed was that you set 
argv_emulation to true in your setup.py file.

Turning off argv_emulation seems to rectify the issue, at least on my 
system. The wrapped app launches and the toplevel window displays as 
expected.

If you require argv_emulation for some reason, then you may want to file 
a py2app bug on the MacPython mailing list. Otherwise, can you get by 
without it? What purpose is it serving in your own apps?
