Comment 1 for bug 236070

The bug report is valid from a user perspective.

This is, however, due to a design choice of KDE. The changes made are saved to '~/.config/menus/applications-kmenuedit.menu', and reinstalling a package can have no control over this.

From http://docs.kde.org/stable/en/kdebase-runtime/userguide/kde-menu.html :

"Common Pitfalls

Applications not in the menu do not exist with regard to other applications or file associations: If you remove an application from the menu, KDE assumes you don't want to use it.

When applications are unwanted in the menu, either place them in .hidden menu or a dedicated menu with

NoDisplay=true

in the .directory file"

As said, from the "design perspective" this bug may be classified as "Invalid", but it does not remove or negate the negative user experience. The best option (from a user perspective) would probably be for 'kmenuedit' to have a separate tickbox for "Hide this menu entry". I do not know if this is done/planned in KDE 4.
