Workaround for the time being is to use:
-vf format=yuv422p,cropdetect=24:16:0
(or format=yuv420p)

Note that if I understand your usecase correctly, 
the following should be significantly faster:
$ ffmpeg -i input -vf cropdetect -f null -

> I've tested with 2.5.4, 2.5.5, 2.5.6, 2.6, and 2.6.2.

For future questions: Please understand that you 
should (and must) only test current FFmpeg git 
head, nothing else is relevant here.
