That sounds very reasonable.

Mh, nope. There's no error message, because there was no error, as far
as X2Go Client/nx is concerned. A command was successfully started and
terminated. Although a "stray" bash process is not what the user
*intended* to get, it's what the command ultimately did.

The only way to detect a session almost immediately terminating is to
track the time between x2goruncommand start and session termination. If
that's too low, say, under a minute, print out an error message. But
this will also cause a false positive if the user really *intended* to
terminate the session very quickly - for whatever reason. Maybe because
it was meant as a quick test to see if X2Go is working at all.

I'd like to avoid such ambiguity.

I can generally change the error message Chris did get by sheer "luck"
the second time around, but the point is that this (in this special case
unhelpful) error message doesn't even come up reproducibly -- because a
successfully created or attached session terminating is in general no
error, as explained above.
