Taxonomy filters by this plugin not working with WP Document Revisions

[PeterM-9]

Hi,
I am starting a document managemet system using the WP Document Revisions plugin. I created two extra taxonomies for my documents (documenttype and docyear) and would love to use Admin Taxonomy Filter to add filter dropdowns for my custom taxonomies in addition to the filters provided by the Revisions plugin.
It is really easy to set up and the dropdowns show up in my documents list page. They are placed before the dropdowns provided by the Revisions plugin. However they are not functional. I can select a term from the dropdowns (generated by Admin Taxonomy Filter), but when I hit "Filter" nothing gets filtered and the dropdown reverts to the "Show all..." state.
Incompatiblilty to the Revisions plugin? A mistake of mine? Or is there a solution?
I am new here creating issues, so please let me know which other info or docs I should provide.
Thanks a lot,
Peter

I really would love to get that working. It would do exactly what I need, if it would work with my "document" custom post type. I have no other plugin which creates its own post types and therefor cannot check, whether it is a problem of the document revisions plugin. If you can point me to the suspect areas in the code, I could try and help solve the problem with your support.
Thanks a lot
