When using unusedfiles.py on en.wikisource.org, the UnusedFilesGenerator returns nothing. I presume that this is due to MediaWiki changes in the HTML interface for "Special:Unusedimages".
My changes to make my bot functional are found here:

The current patch is attached, and I am happy to work on any suggestions on how this patch can be improved.

I see you have disabled the Page: check code. That is required on wikisource, which uses the ProofreadPage extension. This is a workaround for a mediawiki bug? When the image is used by a ProofreadPage, it still appears in the mediawiki list of unused images.
