Apologies I must have missed/spam-bucketed it.

yes, libgsf is not currently designed to be unloaded.  It would be a
fairly trivial change though.  We could look into offering a
    void gsf_dynamic_init (GTypeModule *mod);
    void gsf_dynamic_shutdown (GTypeModule *mod);

It's difficult to do that without knowing what version you forked
from.

PS
    1) Could you correct the copyright assignments ?
    2) You'll want to update your version of libgsf.  0.12.0 came
    out today with several fixes for OLE2 meta data streams.
