[Bug 29061] Theme schemas corrupted or missing

[Johan Brannlund]

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

Description:
I'm running a current Dapper on AMD64. Since a week or so, no icons
appear in the gnome panel menus, only text. I thought I'd try a
different theme to see if that corrected the problem, but running gnome-
theme-manager only gets me a dialog box saying

The default theme schemas could not be found on your system.  This means
that you probably don't have metacity installed, or that your gconf is
configured incorrectly.

I have reinstalled the following packages, but that didn't help:

desktop-base
gdm
gnome-control-center
gnome-icon-theme
gnome-themes
gtk2-engines-clearlooks
gtk2-engines-industrial
gtk2-engines-mist
nautilus
gdm-themes
gnome-art
gnome-themes-extras
metacity
tango-icon-theme
