I made this fix to svnlook in 1.6.5.
I think the user who reported this problem reported it on IRC,
so you'd have to search the log of the #svn IRC channel to find
a record of the statement that "enforcer is known to be affected".
I had the user test the patch and has said it fixed his particular problem.
From what you describe it sounds like enforcer is still broken in
some way and needs some kind of fix. I'd encourage you to try to fix
this yourself and submit a patch if you can.
Thanks,
