The above did not work for me under 2.x. I also attempted to skipto HEAD (svk sync -s HEAD //mirror/path) which failed. Finally, I detached the mirror and rechecked out to a new path (using the skipto option of sync to spped up the process).
UPDATE: That did not work due to the bug below. Fixing that bug still resulted in the REPORT request failed error.
