[B.A.T.M.A.N.] -p ... crashes

Hi,

i've seen this behavior bevor, but couln't reproduce it until now:

If B.A.T.M.A.N.-III v0.1.1 beta2 (compability version 2) is startet with a -p(refered gateway) option and the given gateway is (at least) 2 hops away (may also not/-always/-directly reachable after start), batmand crashes.

This happens reproduceble ~30-60sec. after start. Until this point routes are written. No output. No purging of written routes.

Tests used: batmand -p <gateway> -r 2 eth1:bat br0:bat

With a 1-hop-to-prefered-gateway enviroment batmand seems to have no problems...
