Yea, not many of the developers hang around here just a whole lot. They're generally on irc though. Here's the post about that with the server.
" 2) join the irc channel #gtk-gnutella on the server irc.freenode.net. A irc client for unix systems would be for example irssi, kvirc or xchat, on windows best choice is mIRC.
Ask there. You'll maybe have to wait when noone is alive, though, so be patient."
Hope you can get some help.
