Thanks for providing the repository. After examining your filesystem
a little bit, I have bad news and good news.

The bad news is that what looks like a bug in 'svn log' or 'svn blame'
seems instead to stem not from the harvesting of FS information, but
from the information itself. I have identified what I think is a bug
in the core of libsvn_fs's algorithm for choosing copy-IDs for use in
the DAG layer.

The good news is that this bug shouldn't affect your data, and once
fixed (testing a fix right now, in fact) should allow your (and
everyone else's, sadly) repository to be repaired with a dump/load

If indeed this bug is a real bug, and is the cause for the problems
you're seeing, I accept all the blame for it -- it was my oversight.
