Caveat: The below is based purely on a quick look at the relevant
"svnadmin help" output, *not* on personal experience.

I suspect data corruption in your svn repo.  Try running
"svnadmin verify" on it.  If that does indeed report problems
(well, maybe even if it doesn't...), look into "svnadmin
recover".

As always in such circumstances, tread carefully!  Take a backup
before attempting recovery, etc.  As with any such recovery tool,
there's always the risk that "svnadmin recover" might in fact
make things worse.
