Comment 1 for bug 780346

When the global menu option is in use, gnome-mplayer has no way of detecting that the menu is not actually in the window. Recently in SVN (v > 1.0.3) a gconf/dconf key was added named "enable_global_menu" this option should be set to TRUE when the gtk global menu is enabled.

I asked in launchpad on how to automatically detect the global menu feature so this key would not be needed, but the question was ignored.

See gnome-mplayer bug

gnome-mplayer packagers will need to patch the gconf or dconf xml schema to set the correct value to true so that the option is enabled properly.
