for me, gp was eating up to 90 % removing menu-xdg solved the issue, though it forced me to also remove the side kubuntu packages. As some others, I'd like to keep both. So a long term solution would be appreciated ;-)
Also note that it had side effect, like the one mentionned in lp bug 57516... -- gnome-panel eats 50% cpu for half an hour and flickers https://launchpad.net/bugs/52405 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
