Sorry, there was no punctuation on that line...

su -
and not
su

(From the su man page ...

     -l      Simulate a full login.  The environment is discarded except for
             HOME, SHELL, PATH, TERM, and USER.  HOME and SHELL are modified
             as above.  USER is set to the target login.

     -       (no letter) The same as -l.
)

It may be that (typical of linux/unix) the commandline version
of su has more features available than the gui version.

I also liked the suggestion to use
os.system('command &')
and see if that makes a difference...
