Comment 2 for bug 98547

Hari,

That is the menu item for the Debian menu, which is not used in Ubuntu. Ubuntu uses the freedesktop.org standard for menus. The menu items are .desktop files located in /usr/share/applications/

As for the original bug. This is a bit of an issue. According to the freedesktop.org desktop file spec Science isn't a toplevel menu entry. Education is the closest thing. So this isn't even really a Gnome issue, I don't think.
