Public bug reported:

Package:  xvnc4viewer 
Version:  4.1.1+xorg1.0.2-0ubuntu4 

I use UltraVNC-based SingleClick to support windows users:
http://www.uvnc.com/pchelpware/creator/index.html

I've created a remote support application using their tool
(http://www.uvnc.com/pchelpware/creator/index.html) and have used it for
over a year to display Windows users desktops on my Ubuntu box.  My
regular motion is to run "vncviewer -listen" via terminal and then have
the windows users connect to me.  Up until Gutsy and the new xvnc4viewer
version, this worked wonderfully and I'd call this a regression.

Now, I can still listen for people who use other VNC servers such as the 
UltraVNC server full edition, but not from SC.  After some further perusing 
into the problem, I have a hunch it may be related to the RFB version of the 
server?  The feedback I get back at a terminal for a working connection is as 
follows:
Mon Jul  2 14:25:18 2007
 CConn:       Accepted connection from 192.168.2.197::3707
 CConnection: Server supports RFB protocol version 3.6
 CConnection: Using RFB protocol version 3.3

Mon Jul  2 14:25:20 2007
 TXImage:     Using default colormap and visual, TrueColor, depth 24.
 CConn:       Using pixel format depth 6 (8bpp) rgb222
 CConn:       Using ZRLE encoding

Mon Jul  2 14:25:21 2007
 CConn:       Throughput 20085 kbit/s - changing to hextile encoding
 CConn:       Throughput 20085 kbit/s - changing to full colour
 CConn:       Using pixel format depth 24 (32bpp) little-endian rgb888
 CConn:       Using hextile encoding

Mon Jul  2 14:25:36 2007
 main:        End of stream


And for the UltraVNC SC server (which worked in the old vncviewer in feisty), I 
get:
Mon Jul  2 14:21:22 2007
 CConn:       Accepted connection from 72.54.229.147::51545
 CConnection: Server supports RFB protocol version 3.16
 CConnection: Using RFB protocol version 3.8

Mon Jul  2 14:21:44 2007
 main:        End of stream

In this case, I made the end of stream happen by ctrl+c.  It just sits
and waits for a long long time.  I've tried using hextile as the
PreferredEncoding, but that doesn't seem to help either.
