Public bug reported:

Scenario:

User A is a member of group G.

.vnc (inside user A's $HOME) is owned by other user B and group G.

when user A runs vncserver, it complains that "wrong type or access mode
of .vnc", even though vncserver has permission to read and write every
file within that directory (by virtue of group G).  There appears to be
no way to specify that vncserver stop complaining about this situation.

I realize that this is a very rare case. Specifically it applies to
PiCloud, where the owner of files in user X's home directory are not
necessarily user X.  I realize this is not best practice, but it is
necessary due to issues with our DFS and AUFS (see
http://blog.picloud.com/2013/05/01/using-aufs-and-lxc-to-manage-
dependencies-at-cloud-scale/ for an overview of what we are doing).
Until vncserver, we had not run into an application that complained that
its access was being derived from the group, not ownership.

If there is a way to disable this check, it'd be most helpful.
