It could well be a race condition...

My guess is that on the first press, it sends the kill signal to 
mythfrontend, but then when it tries to start it again, the old instance 
hasn't finished exiting causing the new instance to fail to start (ports 
already in use etc...).  On the second call, it will start successfully 
because by then the old instance has exited.

You could test this by adding a sleep in between the 2 commands.

thanks,
Alex
