Hi,
I have the segfault when I once enter an item (ellipse, rectangle, whatever) and
then move in the canvas (without even clicking). I get :
Gtk-CRITICAL **: file gtkobject.c: line 1118 (gtk_object_ref): assertion `object
!= NULL' failed.
Gtk-WARNING **: invalid cast from (NULL) pointer to `GtkObject'
Segmentation fault
See ya !
