I now ran Automatic Update and it seems to be fine again:


Before:

# strings /usr/lib64/libsvn_subr-1.so.0 | grep canonicalize
svn_path_canonicalize
svn_dirent_canonicalize
svn_uri_canonicalize
svn_opt__arg_canonicalize_path
svn_opt__arg_canonicalize_url

After:

# strings /usr/lib64/libsvn_subr-1.so.0 | grep canonicalize
svn_path_canonicalize
svn_relpath_canonicalize
svn_dirent_canonicalize
svn_uri_canonicalize
svn_fspath__canonicalize
svn_urlpath__canonicalize
svn_opt__arg_canonicalize_path
svn_opt__arg_canonicalize_url


zypper history shows

/var/log/zypp/history:# 2014-08-06 18:27:27 subversion-1.6.17-1.27.2.x86_64.rpm installed ok

So that must have been it.
