argv[0] and the name of the script aren't necessarily the same thing.
__file__ is the file of the script (all modules have a __file__
attribute).

What you really should do at this point is print out your environment
variables to make sure they're the right thing. If the environment
variables aren't the problem, then you probably forgot to include the
shell script in your app.

When I want to open something in Terminal I generate a temporary
script on the fly, rather than having some static script with
parameters wedged in with environment variables. There's even an
example of this technique in the py2app source:
