Which version of nautilus (err.. Gnome) were you using?  The one in Edgy
or Feisty?

I ask, because Edgy seems to not want to run executables at all from
double clicking, producing this horrendous error:

I've been told the above is a bug in nautilus.  At any rate, it
partially resulted from removing the MIME contents of Wine from the
packages; this was done for security purposes, and because
binfmt-support is supposed to launch the app with Wine.  You'll notice
in the above image that it does indeed identify the application
correctly - nautilus just fails to launch it.

That said, I maintain the Ubuntu packages, and if you've got a fix I can
use, I'll certainly incorporate it.

Thanks,
