The connection with IPv6 leads me to believe that this is
http://bugs.gentoo.org/250468
http://sourceware.org/bugzilla/show_bug.cgi?id=7060

Mike has added a patch to Gentoo's patchset but hasn't bumped the

Anyway, if this is your problem, it looks like upstream is already
working on it and that we just need to *prod* Mike a bit to get a fix
