Volume Control Applet complains and crashes

[Jaap A. Haitsma]

When I right click on the volume control and choose open volume control 
I get 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.

If I then click on details I get the following error info

Bad key or directory name:
  "/apps/gnome-volume-control/OSS-SigmaTel_STAC9721/23-1/Vol  ": ` ' is 
an invalid character in key/directory names

These keys are indeed not present in gconf, but I guess they should
have been there automagically. If I then close the window it crashes and 
comes with the following error??


Application "gnome-volume-control" (process 7859) has crashed
due to a fatal error.
(Segmentation fault)

Anybody else experiencing this??
