Hello gtk-gnutella shipped with OpenBSD 4.0 is now obsolete and obsolete versions are banned after 1 year from the Gnutella network.
If you are wondering, why it's suddenly not working, uninstall gtk-gnutella, download the official one, delete ~/.gtk-gnutella, do Configure -d, make, make install and it should work again. It worked just fine for me. CL<
