Looking at =

http://svn.gnome.org/viewvc/conglomerate/trunk/src/cong-editor-widget3.c?vi=
ew=3Dmarkup
both places that call the callback pass user_data using
GUINT_TO_POINTER, so replacing the
  (gboolean)user_data
with:
  GPOINTER_TO_UINT(user_data)
should work and fix this on both 32/64 bit archs
