Public bug reported:

Affects: gnome-panel (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


Description:
Binary package hint: gnome-panel

I set my Xorg.conf up to use dual monitors, no xinerama, no twinview.
I'll include my xorg.conf below for reference.

The problem is, when I click on the 'background' tab in the properties
dialogue for the top panel on my second monitor, the panels on both
monitors crash and restart.  This problem is repeatable and only happens
when in the dialogue for the panel on the second monitor.  The
properties dialogue for the panel on the first monitor works properly.

My xorg.conf for reference:
