Gnome problems

1. gnome-panel 2.28.0 has a bug in Karmic Koala. When you set it up to auto-hide it starts looping and takes almost all CPU. And auto-hiding does not work. One cannot even get back to the access to panel settings to disable auto-hide. You can start gconf-editor and under panel->toplevels->top_panel_screen_0 disable auto-hide option.
