svn checkout fails

Is it normal that svn checkout of http://svn.openstreetmap.org/sites/rails_port/ will fail?

Error: PROPFIND request failed on '/rails_plugins/daemon_generator/trunk/generators/daemon'
Error: PROPFIND of '/rails_plugins/daemon_generator/trunk/generators/daemon': 405 Not Allowed (http://svn.kylemaxwell.com)
svn --without-externals

Or something similar… Externals will often fail with svn.
