in fact there were also many segfaults triggerable with
ip addr del
ip addr add
especially on the main olsrd interface, if you do it often enough,.. )-;

hennig hannes and me were checking this today
hannes already commited a first bugfix for them,..
but in fact this just caused ne segfaults,..
even without an ifupdown or ipaddr adddel script running,.. after about 5
