It seems this hackery with xdotool [1] works, essentially doing the 
equivalent of focusing the rosegaden window and simulating a CTRL+Q 
keypress:

xdotool windowactivate $(xdotool search --all --onlyvisible --pid 
$(pidof rosegarden)) key --clearmodifiers ctrl+q

But, if the open file is unsaved, like with a 'normal' quit rosegarden 
will prompt to save. Not sure if this still works for you. Maybe you 
could concatenate with and && two similar commands first simulating 
ctrl+s and then ctrl+q, but that might or might not be desired depending 
on the use case.

Otherwise I guess that some (Unix) signal catching code should be added 
within rosegarden, but I'll leave that to Ted et al. to answer :-)
