[B.A.T.M.A.N.] batman-adv: Unable to add interface in LXC

I am running LXC (SID) under Debian SID and the current git version of
batman-adv (v3.7-rc7-1325-gaf5d4f7) +batctl (v2012.4.0-30-ga395164).
But it fails to add any of my interfaces and non-batman-adv interfaces
can be created without problems
