[Natty] Ubuntu's Gnome desktop behaviour overlaps on KDE plasma

[Swâmi Petaramesh]

On an machine where both ubuntu-desktop and kubuntu desktop are installed, when running a KDE session, the system shows a number of undesirable "automated Gnome behaviours", such as seing Gnome-keyring asking for keys at KDE logon, Nautilus opening a folder when an USB key is inserted (where Nautilus is not welcome as a file manager in a KDE session), a Gnome dialog asking for a decryption key where a removable media with encrypted FS is insterted, etc, etc.

KDE behaves perfectly well and doesn't influence Gnome behaviour when Gnome runs, OTOH and unfortunately, Gnome automated things run in KDE when not expected to.

Removing everything Gnomey from ~/.config/autostart/ doens't help either.

Is there a way of completely disabling all "undesired Gnomey stuff" to happen automatically when running a KDE session, besides uninstalling Gnome Ubuntu-destop ?

The goal is to be able to run both environments on a given machine, so users can prefer Gnome and others KDE, without having environments to overlap.
