Unfortunately it's not just a few instances of bogus metadata (commit timestamps and authors), there are also a cases where the git conversion misrepresents the operation performed and makes for confusing history. One example of this is r306097 / df422cbea30e. A file that had been removed in head needed to be restored, and in SVN it was done by copying from the stable/10 branch. The git converter interpreted that as a merge, and then grafted the post-branch stable/10 history into head as a result. That is why we have a bit over 9000 stable/10 commits showing up in 'git log origin/master'.
