Launching application made with py2app
===

I have an application made with py2app that launches from the command line. It also launches if I open the package contents and double click on the main file. It does not however open when double clicked on with the Finder. 
the command line which works is 
/source/pyside/dist/Simple\ Dialog.app/Contents/MacOS/Simple\ Dialog 

the output when double clicking on Simple Dialog within Contents/MacOS/Simplie\ Dialog is
/source/pyside/dist/Simple\ Dialog.app/Contents/MacOS/Simple\ Dialog ; exit;

I am looking for a way to make the application launch from Finder.

Thanks :-)

Cheers
