Error in gnome-volume-control

[Santiago Erquicia]

When I try to open gnome-volume-control under beta2 (installed from the
CDs without upgrading my RH9 installation) it shows the following error
message:

An error occurred while loading or saving configuration information for
gnome-volume-control. Some of your configuration settings may not work
properly.

and in the details:

Bad key or directory name:

character in key/directory names

Does anyone have the same problem?

I don't know if matters, but I have two tabs on the volume control
saying Unknown.
