segfault on glade errors in 0.8

I just installed regexxer 0.8. The first time I ran it I got the following errors:

(regexxer:9834): libglade-WARNING **: could not find widget creation function

(regexxer:9834): Gtk-WARNING **: gtk_scrolled_window_add(): cannot add non scrollable widget use gtk_scrolled_window_add_with_viewport() instead
