Create links - underscores to dashes in paths?

At some point (I do not know when exactly), as my Drupal build changed, the Create links stopped to work.

The path of the Create [content profile type] links leaves underscores unchanged in the name of the type and it should probably change them to dashes.

This needs to be done, I think, in content_profile.theme.inc in function content_profile_default_path_hanlder($action, $arg).
