Is it possible that it's not the bug of gnome-session (I was reported as)? Maybe it should be moved to the right package, at least deletion of /etc/X11/Xsession.d/20desktop-profiles_activateDesktopProfiles helped, and that file is part of pacakge desktop-profiles and "rdepends" on edubuntu-menueditor according to apt-cache. But that package exited in natty too before I upgraded (and I still has it on other natty systems without problem), so it should be some kind of regression.
