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. -- Brane
