Gnucleus development seems to have stopped. Swabby removed the two support forums over gnucleus.com and no updated have been made in the code since july 13th. The website is linking to Gnucleus 1.0.2.6 and GnuCDNA 0.9.4 which are way outdated (more than 3 years ago)
Maybe I'll have to email Swabby...
My advice is you switching to another P2P.
Ciao
