Comment 12 for bug 443133

I've been looking to the issue again today:

$ grep gettext /var/lib/gconf/defaults/* | wc -l
2829

$ sudo gconf-schemas --register gnome-screenshot.schemas

$ grep gettext /var/lib/gconf/defaults/* | wc -l
6

$ sudo gconf-schemas --register-all

$ grep gettext /var/lib/gconf/defaults/* | wc -l
2829

The gettext attribute is being cleaned when registering a schema (gconf-schemas is a wrapper to register schemas used after the installation) which explains why the descriptions are not translated. When the gettext attribute are there the descriptions are translated correctly but still not the default schemas value (using the karmic version on Robert's update)
