Subversion 1.9.3 had a bug where it made incorrect assumptions about old
repositories without a "db/format" file.  This is the most likely cause for
the errors you're seeing.

This bug has been fixed starting from version 1.9.5, so you might want
to try accessing the repository with a more recent version.  Alternatively,
you should be able to use any of the 1.8.x versions, as they didn't have
this bug.

If using a different version is unfeasible for any reason, you can try a
workaround by manually creating a "db/format" file containing "1\n" within
your repository.

Also, please note that dump and load is not required to access your data
(even for old repositories) with newer versions of Subversion, as these
newer versions are fully compatible with all previous repository formats
and can both read and write to them.

Hope this helps!
