Please describe the problem:
When gnome-window-properties (i.e., "Window Preferences") is used to select the Title Bar Action: "Maximize Horizontally", the value that ends up in gconf appears as "toggle_maximize_horiz".

When selecting "Maximize Vertically", the value appears as "toggle_maximize_vert"

According to the descriptive help provided for that configuration item by GConf Editor, the appropriate value should be "toggle_maximize_horizontally", "toggle_maximize_vertically", etc.

Steps to reproduce:
1. Using gnome panel system menu (preferences menu), activate "Windows" (gnome-window-properties).
2. Select Title-Bar Action: "Maximize Horizontally", and close.
3. Logout/Login or reboot
4. Using gconf-editor, inspect apps/metacity/general/action_doubleclick_titlebar


Actual results:
The action_doubleclick_titlebar value is set to 'toggle_maximize_horiz'.

This results in the following ~/.xsession-errors log entry:
"Window manager warning: GConf key '/apps/metacity/general/action_double_click_titlebar' is set to an invalid value", apparently being truncated at 

As a consequence, when the user double-clicks on the title bar, the window is simply maximized (default), 

Expected results:
The window should instead be maximized horizontally, vertically, etc., according to the user's selection in the gnome-window-properties.

Does this happen every time?
This happens every time.
