hi alex

i freqently get olsrd crashes on osx possibly related to sleep/wakeup  
or interface changes. i've attached a typical crash log entry below.  
it is not this very problem you are experiencing but probably a  
related one. as far as i remember the crash occures as soon as i shut  
down my wireless interface. i did not investigate it further because  
i just launch olsrd if i need it. could you please explain why it is  
nessesary to add a "pure" destination route before adding netmask +  
gateway?
