Can not change background

[Mark Blakeney]

Gnome shell on Ubuntu GNOME 13.10 crashes nearly every time I change the 
background as I commented on https://bugs.launchpad.net/ubuntu/+source/
gnome-control-center/+bug/1196196. The Ubuntu maintainer there stated 
that bugs due to ppa's can not be reported on launchpad(?).

Most using Ubuntu GNOME would be using the gnome3 ppa at least, and 
probably gnome3-next as well. Can we not report bugs on launchpad? Where 
should we track them?
