Situation: Upgrade from 6.0 to 6.1 The menu items on the main menu do not match the menu items in the menu edit. On the main menu under graphics/Gimp is listed twice. On the main menu under Multimedia/xmms is listed. In the menu editor under graphics/Gimp is listed once. In the menu editor under multimedia/xmms is _NOT_ listed. These are the most obvios example of the problem.
It now seems the Gnome Main menu is a Combination of the Gnome menu and the RedHat menu. The Main menu = Gnome Menu + RedHat menu. I have not seen the config to remove this aggragation.
I have verified this on a system upgraded from 6.0 to 6.1. I am reassigning this to a developer.
This is due to a lack of menu-merging code in the menu-editor. The next release of GNOME will (hopefully) fix this. However, as this is a major pain to write, I do not expect it will be done in the old branch.
