You shouldn't call run() yourself. It is for the thread library itself.
I tried your example with cmd='ls -l' and it works. If I put a print
'started' after the xc.start(), it prints that before the output of ls -l,
indicating that ls -l is running in the background. (Of course the actual
order is up to the scheduler.) Maybe running it inside a pygtk program
could be different but I wouldn't know why.
