This error indicates that something has corrupted the file. You can
information about the storage format at:
 <http://svn.collab.net/repos/svn/trunk/subversion/libsvn_fs_fs/structure>

That may help you to repair the file as to make things complete, but may also
introduce corrupted data.

One piece of advice I tell everyone when they setup their repository, is to at
least run 'svnadmin verify' over it every night. That will ensure things
like this don't go unnoticed for a long period of time.

If you post the file somewhere and shoot me a private email about where to
find it, I'll take a look at the file. Otherwise, you can try fixing the
file structure yourself with the information in link above.
