subprocess problem

[Andreas Paeffgen]

Thanks for all the great advice.
I tested all the possibilities. So far no luck. If i start the app from 
a terminal, the solutions work. But not, if i start the app-bundle 
(There is no connection to a terminal)

1. Copied the path to p.subprocess
2. Used the def wich: python function
3. Used shutil

When there is no Terminal, there is no error message / status code message.
