node/add/audio produces a blank page

After enabling the audio module /node/add/audio becomes a blank page. When the module is disabled the page is fully functioning.

Additionally, when the module is enabled I get an error at admin/content/node-type/audio page that says "warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'node_type_form' was given in /home/MY_SITE/includes/form.inc on line 377."

Similarly, on the /node/add page, I get this error "warning: htmlspecialchars() expects parameter 1 to be string, array given in /home/MY_SITE/includes/bootstrap.inc on line 856."

I think these errors are related because they all appear at once and they disappear once the audio module is disabled.

Thanks for any help you guys can offer.
