This is intentional, and the dev-list was forewarned when I posted the
patch for this change and let it sit for almost two weeks before


Be careful that what you *perceive* as 1.2-minus-r12006 as "working"
truly is -- chances are very good that your wcprops contain incorrect
version resource URLs. This hidden incorrectness causes at least
working copies which actually don't work for many ra-dav operations,
or worse, can actually cause commits to modify the wrong thing in the
repository (an edge case, but possible). There are server bugs in 1.0
and 1.1, but they were never triggered. The 1.1 client actually
introduced this bad behavior by exposing the server bugs. It's

The workaround for the problem you now see should be straightforward:

   (cd qq/dev; svn sw http://svn.collab.net/repos/svn/trunk/tools/dev)

After long discussion with sussman, we agreed to move forward with the
r12006 change because a visible bug with a simple workaround is far
less of a problem than a hidden bug with a tricky workaround. And
again, this was all described in the patch I posted.
