** Description changed:

Binary package hint: gnome-control-center

While running from today's daily live (i.e. desktop) natty CD (md5sum
5f1c4376fb3c42742627d9f77e83547e), with gnome-control-center
1:2.32.1-0ubuntu5, I opened System > Preferences > Monitors (i.e. gnome-
display-properties) and successfully changed the resolution from
1024x768 to 800x600, since I am using the live CD to install Natty on a
virtual machine, and I wanted the virtual machine's "screen" to fit more
comfortably on the host desktop.

After finding bug 729057, I opened System > Preferences > Monitors
again, with the intention of changing the screen resolution back to
1024x768 as a workaround. However, when I selected that resolution, this
crash occurred.

+ I am unable to reproduce this bug by re-entering gnome-display-
+ properties; my subsequent attempt to change the resolution back to
+ 1024x768 was successful.
