Yeah, I have (had) the same problem. Don't worry about the qcop thingie, it doesn't seem to matter. The script must be borked, I can start an image directly via "snes9x image.zip", and it works fine. So, there must be something wrong with this script, but I don't mind using the commandline first...
Cheers

Edit: I just realized, the problem probably is that I used the script from the first post, and there are debugged versions available... not anymore, because the attachements of the posts have been deleted. But that's probably MY problem, dunno if it's yours as well *G*
