right, almost forgot about that one, we had
problems in 1.9.2.x with userspace (glibc) assuming
certain things about the ipv4/ipv6 addresses
(namely interface being present when ipv6 addr is
listed) which where not guaranteed (because ipv6
isn't supported with vserver yet), but this was
fixed in recent releases (1.9) but not in 1.2x,
which definitely doesn't support ipv6 in any way.
and segfaults where the result ...
