This issue is reported on the dev-list, you can find the thread here: http://svn.haxx.se/dev/archive-2006-06/0857.shtml A few days ago I switched the mechanism of setting up a sandbox for a python test from checkout per test to checkout once+relocate. This works fine for ra_local and ra_svn, but it seems one test is failing on ra_dav: commit_tests.py 13. I'm testing on Windows XP with current trunk. That test basically deletes a file, commits, sets a property on the parent folder and then expects the resulting commit to file with an 'Out of date' error. It worked well before, and if I remove the change in sandbox setup mechanism the test succeeds. I extracted the reproduction recipe in a new test in switch_tests.py, hereby attached.
