Comment (by sbressler):

 Attached is a patch that fixes this issue. I decided to address the issue
 in the constructor rather than before the classes were output so that we
 can address any other uses of $args that might be added later to the file.

 While $args['singular'] might be empty, there is no harm to running it
 through sanitize_title as well. However, that line could easily be wrapped
 in `if ( $args['singular'] )` if performance is a concern.
