Novell bug: https://bugzilla.novell.com/show_bug.cgi?id=345925

===
Running FACTORY version of GNOME, if you press the caps lock key, I get a
dialog box that comes up saying:
  "An error occurred while loading or saving configuration information for
gnome-settings-daemon. Some of your configuration settings may not work
properly."

The details of the error box says:
  "Bad key or directory name:
"/desktop/gnome/peripherals/keyboard/host-3(NXDOMAIN)/0/numlock_on": `(' is an
invalid character in key/directory names"

For some reason I have my hostname set to "3(NXDOMAIN)" due to some other
networking errors and using a hotel wireless network.  It is not the same
hostname that was when gnome started up.

I'm guessing that we need to "sanitize" the hostname variable to be something
that gconf would allow as a key/directory name.

I'll attach a patch. I couldn't test it since my compilation chain is broken right now.
