vnc viewer on ubuntu 8.10 core dumps

Firstly, getting the vnc viewer going was a whole bunch of pain (especially having it log in as non-root). But once I actually did get it going, I saw the following core-dump.

TXScrollbar.cxx:47: void TXScrollbar::set(int, int, int, bool): Assertion `limit_ > 0 && len_ >= 0 && len_ <= limit_' failed.
Aborted (core dumped)

I get that anytime I try resizing or maximizing the window. Not expected behaviour. Since I don't have the time right now, I'm simply going to live with not resizing the window.

There are other issues with VNC that I haven't been able to sort out yet:

1. running VNC automatically on startup (or rather having xinetd configured so that Xvnc would be launched each time a user tries to connect.
2. to have the vnc session match the current users desktop session on the server
3. running VNC as someone other than root
4. running vnc over ssh and xdm so that the same login screen maybe used instead of special VNC protocol

setup:
client machine: ubuntu 7.10 connected via 802.11g wireless
host machine (server): ubuntu 8.10 connected via ethernet eth0 / bridge to wireless network
