I know it's harsh, but let Red Carpet's "Verify Installed Packages" thing have its way with your system, noting anything major that it removes (cuz you sneak in behind its back and put all that stuff back later ;). This often entails a chunky (>50MB) download, but is worth the effort.
I've had *no problems* with Red Carpet, and that's with me being installed to all but one channel (that channel being Opera, because QT apps look sucky on a GTK desktop and Mozilla and Galeon eat its lunch anyway), with a slew of GNOME 2 preview stuff floating around...
Anyway.
Where was I?
Oh yes.
