gnome hangs when clicking 'Desktop' menu

[Brendan Simon <Brendan@BrendanSimon.com>]

I have debian etch, with gnome installed.  I connect via vnc and have 
'gnome-session &' in my .vnc/xstartup file.  It seems to work fine but 
hangs when ever I click on 'Desktop' on the menu/panel.  All other menu 
items work as expected, until 'Desktop' is clicked, then everything 
stops responding.

Anyone know why and/or how to fix this?

Thanks,
Brendan.
