The revision before that one is the same :)

IIRC, this was a faulty commit done by the tigris admins (back when the
repo was hosted on tigris.org), but then removed later because it
contained non-public data.
You can remove revisions or data from revisions using svndumpfilter if
you have to.
Of course, in this case the whole commit was removed. You can however
only remove the committed files but leave the message and all other
metadata intact, and I know of some users who have revisions like that
in their repositories.

And those two revisions caused a lot of problems already, because that's
really a special situation which we don't always check for in the TSVN
code ;)
I remember a lot of problems because of revisions like these, especially
in the revision graph.
