Bug#496017: Whoops, spoke too soon. Error messages persist even

[Dominique Brazziel <dbrazziel@snet.net>]

after the VNC server is started and listening on port 5901.  This bug
seems similar to bug #503880.  The messages start up as soon as I start
the second ssh session with port forwarding.

In my instance, the channel type appears to be 'listening for inet X11
connection' (according to channels.h):
