[Help-gnunet] GUI quits when searching or inserting file

[edward]

Hi,
Just installed GNUnet on a PC running Fedora 3 and Gnome.
gnunet-transport-check runs OK, several peers are located by a ping and 
the deamon seems to startup and run OK (gnunetd -d). But 2 problems occur :
After a few minutes, the server outputs the following message regularly 
: "WARNING: Announcing ourselves pointless : no other peers are known to 
us so far".
The GUI (gnunet-gtk) quits when a search is initiated or when attempting 
to insert a file. The same message appears in the console in both cases 
: "Segmentation fault".
Any clue what's going on ?
