The trouble with abusefilter, is that quite small changes can have unintended consequences. That's why we generally suggest you only use it if you know and understand the code you are adding.

I can't really debug that filter for you, but you could either ask on the wiki where you found it, or in the forums here; somebody may be able to straighten it out.
