At the bottom of check_markup() the function adds t('n/a') to the output in the case of unset input text. I think it should simply be set to the null string. Creating content when the user intends there to be none is problematic.

"n/a" only appears if the current user does not have access to the text format the text should be filtered with. If this string appears, then most likely some code elsewhere is wrong.
