Hi, can you please post the commandline with which you started the iodined server? (mask your -P argument, i'm interested in tunnel_ip/netmask)

./iodined -f -c -P PASS 10.7.0.1 tunneldomain.de -DD
It don't crash when the "Tunnel Nameserver" in the app is not empty.
Sry for my bad english :P

The tunnel IP in the commandline was before 10.8.0.1. I changed only to 10.7.0.1.
