Hi Albrecht and Mario,

In my case, launching balsa somehow also includes running dbus-launch,  
but I guess it can't communicate with any of the running dbus-deamon  
sessions.    Even if it did, it wouldn't make sense to pop up a message  
on the server (which might well not have X running anyway.)  Running  
dbus-monitor in my kde session, I see no activity from balsa, but  
running it in the console from which I launched balsa, I do see various  
messages, and eventually what I think it the timeout error.  I wonder  
if dbus could be configured to launch a daemon if none is found, and  
popups should get properly redirected through the ssh tunnel.  Anyway -  
that would be a dbus enhancement or configuration, not a balsa thing.

What is still not clear to me is why all I get is a timeout note to the  
console, but Mario gets a freeze (it's still not clear what a "text  
popup" is).

Ah! - see the AUTOMATIC LAUNCHING of "man dbus-launch".  It seems to  
imply that dbus-launch might actually launch a new dbus-daemon, but I'm  
not certain.  I do think that info might point in the direction that  
needs to be followed, but it's going to take me a while to actually  
understand it all.  It's also not clear to me where in the ssh/balsa  
launch process that the dbus-launch is actually getting called.
