I believe that IDLE sets up some kind of debugging
connection to its child process. That number might
be a processs ID or port number or something related
to that.
I tried to hunt down where the problem occurs, but I was led
to the method "application_openFile_(self, ns_app, path)" in the
class _PyGui_NSApplication. I couldn't find out how this method
ever got called though.
It's called by the Cocoa framework to handle files
passed to the application from the Finder. It also
seems to get called when there are command-line
arguments. But it works on the C-level argv, which
means it can pick up stuff that doesn't normally
end up in sys.argv. The check for sys.argv[0]
is there to work around one of the side effects of
that. It appears that you've encountered another
one.
I'm using a different method of dealing with
this now, which will probably fix your problem as
well. I've attached a replacement for
GUI/Cocoa/Applications.py. Let me know if it
works for you.
