The version applied to Ubuntu Precise was a backported version of the
upstream v12 branch.  So I suspect much of the issues are coming from
that being a backported version.  For Ubuntu Quantal I have reverted
what we had and pulled a clean v12 plus the security fix we had on top.
I have then applied similar fixes to pull that forward to v3.4-rc4 and
it seems to pass very light touch testing here:


I am pushing it out for perusal as people are asking me about it.  This
includes an updated permissions fix.
