Actually this could be quite a problem, because FSFS format version 5
was never present in any official release of Subversion. According to
our release notes, it appeared in some 1.7.0-alpha versions, but
official 1.7.x uses format 4 (as does 1.6.x) and will error out if it
sees a format 5 repository.
Someone must have played a little loose with pre-release code on a
production server.
