OK, here's another packet capture. I spent some time trying to find the minimal checkout that would demonstrate the problem, in order to minimize the size of the capture. It turns out checking out several zero-length files will not trigger the problem. (It would, however, trigger the original issue the patch was trying to solve.) Checking out a single file with some text in it works, though, so this is a checkout of a single file called "a.txt" inside a directory called "bsd-test". --00163646d8e289dff0048fc737d3--
