I've just done a fresh (2h) cooker install with just gnome2 and I note that it's very unstable (nautilus, gnome-applets, gnome-panel). If someone know why, let me know.
I have a big problem with MMboX (it's in contribs, I'm a MMboX dev) too. It worked fine with a 2 weeks cooker, works fine one a Debian box but crash now (Fatal signal: Segmentation Fault (SDL Parachute Deployed). ) :( Thanks for help, Florent
