Great question. I tried the realvnc based xvncviewer and the problem did not occur.

brad@bklaptop2:~$ xvnc4viewer --version

VNC Viewer Free Edition 4.1.1 for X - built Apr 16 2008 13:02:40

This one dies horribly. Apparently on resolution change, but not certainly.. It does always die on a 
screen mode change though.

brad@bklaptop2:~$ vncviewer --version
TightVNC viewer version 1.2.9
Ubuntu package : xtightvncviewer from 8.04

I'm just building the latest tightvnc from source to see if the issue is fixed there, but 
xtightvncviewer from Ubuntu 8.04 will certainly kill it.
