Breezy Preview 1: gnome-background-properties always crashes

I can't reproduce this on a recent Breezy box - if this is reproducible, could
you please try to obtain a backtrace?

Thank you very much.

Yep, it's always reproducable. I can't change my background color at all.
Sorry, I don't know how to do a backtrace. Could you give me instructions? Thanks!

click on the bug-buddy dialog to send the bug upstream, the window has the
backtrace or use gdb:
- gdb gnome-background-properties
(gdb) run
... crash
(gdb) thread apply all bt

Thanks for the help! The gnome crash handler doesn't appear, btw.
