This bug was fixed by Paul.

Unfortunately, this command line still does not work:
Instead of producing different frames, for every five 
(progressive and interlaced) input frames, four 
progressive output frames are produced, but only three 
different ones: The wrong frame is dropped;-(

The following works fine here for your sample:
ffmpeg -i input -vf pullup -r 24000/1001 out.mkv
