That serialised hash is inside a revprops file. You won't be able
to fix this directly unless you understand how FSFS stores data.
If you really want to know, start reading here:
https://svn.apache.org/repos/asf/subversion/trunk/subversion/libsvn_fs_base/notes/structure
and then this:
https://svn.apache.org/repos/asf/subversion/trunk/subversion/libsvn_fs_fs/structure
I would recommend you reset the mirrored repository to the
last known-good revision (269997?) by moving out of the way all files
belonging to newer revisions (in db/revs) and revprops (in db/revprops),
running 'svnadmin recover' (this should set db/current to the number
of the last known-good revision), and finally editing the
svn:sync-last-merged-rev revision property with
'svn pe -r0 --revprop REPOS_URL'
to write the number of the last known-good revision in there.
Now you should have a working repository that is synced up to the
last known-good revision and 'svnsync sync' should catch up again.
