I forgot to mention that -ofps 24000/1001 did not work either. No parameter
that takes a framerate will accept 24000/1001.  24, 30000/1001, and 30
all work. The only problem is 24000/1001.

Indeed. 

That is just the next most recent version that I have.  I first noticed it
some time ago (maybe a few weeks) but I didn't bother to report it
because I had an older working copy.
