Public bug reported: I updated my 13.10 to 14.04. In GNOME FlashBack (metacity) I get gnome-panel without clock and logout buttons.
If I try to launch gnome-panel manually with gnome-panel --replace I get the following messages in console: (gnome-panel:8898): Gtk-CRITICAL **: gtk_accelerator_parse_with_keycode: assertion 'accelerator != NULL' failed ** (gnome-panel:8898): WARNING **: Unable to parse mouse modifier '(null)' (gnome-panel:8898): Gtk-CRITICAL **: gtk_accelerator_parse_with_keycode: assertion 'accelerator != NULL' failed ** (gnome-panel:8898): WARNING **: Unable to parse mouse modifier '(null)' *** BUG *** In pixman_region32_init_rect: Invalid rectangle passed Set a breakpoint on '_pixman_log_error' to debug then panel starts and looks like before (<=13.10).
