Please describe the problem:
In gnome-terminal, opening the profile editor attempts to set the gconf key /apps/gnome-terminal/profiles/${PROFILE_NAME}/palette .  If that option exists in a mandatory gconf source, this results in an error dialog.


Steps to reproduce:
1. Check that /etc/gconf/2/path has 'include "$(HOME)/.gconf.path"' in it,
before the readwrite source in $(HOME)/.gconf
2. Add the following to .gconf.path:
xml:readonly:$(HOME)/.gconf.shared
3. Set the key /apps/gnome-terminal/profiles/Default/palette in ~/.gconf.shared, perhaps using
gconftool-2.
4. Open gnome-terminal, and use the Default profile.
5. Choose the menu item Edit->Current Profile.

Actual results:
An error dialog appears with the following error message:

Can't overwrite existing read-only value: Can't overwrite existing read-only value: Value for `/apps/gnome-terminal/profiles/Default/palette' set in a read-only source at the front of your configuration path

Expected results:
No error dialog pops up when opening the profile editor.  Instead, the palette controls simply don't allow changes.

Does this happen every time?
Yes, I can consistently reproduce this.
