Status changed to 'Confirmed' because the bug affects multiple users.

Hi,

I am affected by this problem as follows:
- Activate screen lock
- Unlock the screen
- gnome-shell crashes and restarts.

Seems that st_widget_get_theme_node () is not returning anything and causes the crash. Compared the source of gnome-shell from raring (st/st-widget.c) and the same file from Cinnamon (https://github.com/linuxmint/Cinnamon/blob/master/src/st/st-widget.c) and there's one return line missing on the raring version:

          g_critical ("st_widget_get_theme_node called on the widget %s which is not in the stage.",
                    st_describe_actor (CLUTTER_ACTOR (widget)));
          return g_object_new (ST_TYPE_THEME_NODE, NULL); // this one

I'm testing it right now.

BTW:
gnome-shell:
