crash when committing

[Stefan Küng <to...@gmail.com>]

Hi,

I'm going through some crash reports sent for TSVN and I found a crash 
that happens when committing, and the wc has some incomplete entries:

libsvn_wc/node.c, svn_wc__internal_get_origin().

SVN_ERR(svn_wc__db_scan_addition(&status, &op_root_abspath, NULL,
                                 NULL, NULL, &original_repos_relpath,
                                 repos_root_url,
                                 repos_uuid, revision, NULL, NULL,
                                 db, local_abspath,
                                 result_pool, scratch_pool));

if (status == svn_wc__db_status_added)
  {
    if (is_copy)
      *is_copy = FALSE;
    return SVN_NO_ERROR; /* Local addition */
  }

*repos_relpath = svn_relpath_join(
                        original_repos_relpath,
                        svn_dirent_skip_ancestor(op_root_abspath,
                                                 local_abspath),
                        result_pool);


when the status is svn_wc__db_status_incomplete, the 
original_repos_relpath can be NULL, and then the svn_relpath_join() 
crashes because of a null-pointer access.
