Common known problem since some years, looks like still never fixed.
Simone, it depend on you and USAGI now ;-)

BTW: in earlier days, kernel crashes if you removed a not assigned IPv6
address...currently not tested what happen today on removing one of the
double assigned ones...

initscript-ipv6 has a duplicate address detection built-in since long time
(ipv6calc was born to solve this issue longer days before).
