Description of problem:
KNetworkManager is a KDE-Only application, however it appears in the System menu
in GNOME. To prevent that, add "OnlyShowIn=KDE" to the desktop file, with a
patch or with the "--add-only-show-in KDE" option of desktop-file-install
Version-Release number of selected component (if applicable):
knetworkmanager can be used just as well in gnome as KDE.
I don't agree, GNOME has nm-applet which does the same thing and integrates
better with GNOME (gnome-keyring)
same as kpowersave, imo, both nm-applet and knetworkmanager should be
visable/usable from *any* desktop environment.
Being technically usable and being in the menu is a different story. If feels
very strange to have kpowersave and knetworkmanager in the GNOME menu when there
are GNOME-specific equivalents. Knetworkmanager was even developped only to have
a KDE version of nm-applet.
When you have a multiuser system where one user uses KDE and the other uses
GNOME, those applications really look out of place in the other DE's menu.
The same is true for k3b and nautilus-cd-burner, koffice and ooo... and also
works in reverse.
What about a package like kmenu-gnome that moves some programs under different
submenu (GNOME in this case). For example gmenu-kde rpm can move
knetworkmanager, kpowersave... under KDE menu.
