Lucid update: You *can* use gnome application while frei0r-plugins (which installs some opencv packages) is intalled. I tested this with totem, brasero, rhytmbox and software-center in fully updated Lucid Beta1.
Bad news: If frei0r-plugins is installed, launching totem will show the error message but totem will open normally. Uninstalling frei0r-plugins, but leaving the libcv packages will not the show the error message on totem startup.
