Is there an existing svn:sync-lock property on revision zero of the
slave's repository? If so, what does it look like?
svn propget --revprop -r0 svn:sync-lock URL_TO_REPOS

It sounds asif the problem is with parsing the existing property,
which must be done since the lock needs to be checked.

How did the lock-up you mentioned happen? Is it possible that the property
got corrupted during the lock-up? For instance, because the file
containing the serialized lock data was not fully written to disk by
the operating system?

In any case, if the property still exists and no sync job is running
you need to remove it because it will prevent new sync jobs.
Any svnsync process will believe that another svnsync process is currently
writing to the repository.
