[Denny Beyer <denny esru strath ac uk>]

Hey,
by using an exported shape, dia (latest cvs) crashes with following 
error message:


(lt-dia:20259): GLib-GObject-WARNING **: invalid unclassed pointer in 
cast to `GObject'

(lt-dia:20259): GLib-GObject-CRITICAL **: file gobject.c: line 1561 
(g_object_ref): assertion `G_IS_OBJECT (object)' failed

** (lt-dia:20259): CRITICAL **: file fonts.c: line 343 
(pango_font_description_set_size): assertion `desc != NULL' failed
./app/run_dia.sh: line 22: 20259 Segmentation fault  "$DIA_APP_PATH/dia" 
"$@"

thanks,
denny
