For the archives, this is fixed in
http://lists.freebsd.org/pipermail/svn-src-head/2013-May/047921.html
It can be worked around by setting
UsePrivilegeSeparation yes
in /etc/ssh/sshd_config
The default behind the scenes was changed to
UsePrivilegeSeparation sandbox
See the above thread for more information.
