[sugar] request for help - how to restart gabble ?

[Mikus Grinbergs]

G1G1, very recent Joyride.  When on boot my XO fails to find the 
specified jabber server online, it switches to salut in place of 
gabble.  Suppose the jabber server later does join the internet -- 
I would like to try to connect to it.

Is re-starting Sugar (ctl-alt-erase) the only "approved" way to 
re-start gabble, or are there commands which would do it without 
having to re-start the currently running Sugar ?

Thanks,  mikus
