In the xml catalog file that you supply to glade, you are allowed
to specify a "init-function" argument (the gnome catalog does that
to register its icons at startup, also the python support plugin to
initialize the interpretor).

I want you to try to assign the "init-function" and supply one in
your library, from that entry point call your Gtkmm initialization
routines.

Double check the api docs at http://glade.gnome.org/docs, do
you want your type to be written to the glade file as "gtkmm_MyObjectType" or
should it be written out as "MyObjectType" (not sure how this should
look from the GtkBuilder side of things..) ?

Remember we have an attribute for the name of the type, and another attribute
for the get-type-function that you must specify yourself if the type
name is something weird like gtkmm_MyObject.

Hope that gives you something to chew ;-)
