I don't think I can. I tried to find the place *where* this apr_error is
set and couldn't even find that! I thought I could find the error define
that way ;)

Also, I think this *is* the right place to fix this bug (but of course I
don't know the internals that well, so chances that I'm wrong are very

The function same_resource_in_head() calls svn_client__repos_locations()
which returns the error SVN_ERR_FS_NOT_FOUND. And as I see it, this is
correct if the path doesn't exist. But same_resource_in_head() is the
function which should not pass that error on, because it's docstring says:

/* Set *SAME_P to TRUE if URL exists in the head of the repository and
    refers to the same resource as it does in REV, using POOL for
    temporary allocations. RA_SESSION is an open RA session for URL. */

So *SAME_P* must not be TRUE if the URL does not exist in HEAD. Of
course, it isn't true without my patch either, but it throws an error
which it shouldn't in that case. IMHO same_resource_in_head() has to
check SVN_ERR_FS_NOT_FOUND too, because that's just one more sign that
not a 'real' error occurred but that the resources aren't the same.
Other errors like auth failures for example are 'real' errors for that
function too, but not SVN_ERR_FS_NOT_FOUND.

About other RA layers: this function is called from all RA layers, not
just DAV.
