Comment (by dingo_bastard):

 Is this still an issue or is this completely fixed? I added a filter to my
 custom post type, and got the warning pointing to


 {{{
 /wp-admin/edit.php on line 257
 /wp-admin/edit.php on line 342
 }}}

 I removed the custom made filter, and when trying to filter out my custom
 post type by date, I still got the same notice (plus nothing actually gets
 filtered). The code is located here if anyone's interested:
 https://gist.github.com/dingo-d/a770ed318de55dd380ef80b73733abf3

 I checked every part of my code, just to insure it's not something I did,
 but it seems fine.

 Is there a workaround for this?
