After an update 3 days ago gnome-shell stopped working, trying to restart it with gnome-shell --replace only results in another crash and the keyboard stops working.

This is what I get when trying to start gnome-shell:

st_widget_get_theme_node called on the widget [0x24112a0 StButton.status-chooser-user-icon] which is not in the stage.

gnome-shell-calendar-server[4829]: Got HUP on stdin - exiting
Trace/breakpoint trap

If I look in the xorg.0.log I got this error:

gnome-session[5321]: WARNING: App 'gnome-shell.desktop' respawning too quickly

and

: CRITICAL: We failed, but the fail whale is dead. Sorry....

Ran metacity --replace just to get the window borders back for now. The interesting thing is if I log in to xfce I got the same problem, no window boarders, must run metacity --replace in xfce also.

Running Ubuntu 11.10 with gnome-shell 3.2.1.
