I don't think this is a PyQt issue or even Qt one, I suspect this is
related to the app bundle you use for the application or lack of it. I
see exactly the same issue with an Eclipse based application when
starting it from inside Eclipse (which directly runs java with some
commandline arguments). When launching the final build of the
application through an app bundle everything is working fine.

So I suspect that this is related to having an app bundle or some
setting within the app bundle.
