Regarding reproducibility, that's what I was going for with #3. I found another thread, http://svn.haxx.se/users/archive-2009-06/0723.shtml, concluding this error is due to fsfsverify not being current with the latest format, so I'll give the svndump to new repo and redo revision in new repo a try.
