gnome-theme-manager fails

[Jonathan Ryshpan]

Gnome-theme-manager fails, producing the error message:
    No themes could be found on your system.  This probably
    means that your "Theme Preferences" dialog was improperly
    installed, or you haven't installed the "gnome-themes"
    package.

Gnome-themes is installed on my system.

When invoked from a gnome terminal, there are no screen messages.  When
invoked from a KDE terminal, this message appears on the invoking
terminal:
    Window manager warning: Failed to read theme from file
    /usr/share/themes/metacity-1/metacity-theme-1.xml: 
    Failed to open file 
    '/usr/share/themes/metacity-1/metacity-theme-1.xml':
    No such file or directory.
The system is an upgrade to Fedora of a very much upgraded system,
used mostly under KDE.  In a similar system with a fresh installation,
gnome-theme-manager works fine.

Any ideas about what's happening or how to fix it?


NB: I must say that the error message is rather mysterious.  I am a very
experienced computer experience (about 40 years), though not with gnome.
It's not at all clear what the "Theme Preferences" dialog is -- is it a
program, a package, a file, a directory, or whatever?

The message might hint how the installation is improper.  Is something
missing or is something wrongly configured.  If wrongly configured, how?
What could be done to fix the problem?

        Many Thanks:
