Using "-vf fixpts=print" causes Bad mp_image usage count, please report!

Now using r37875 - no difference.

-vf framestep=i,fixpts=print

Using framestep=i got rid of the "Bad mp_image usage count, please report!"
But the PTS still goes out of sync. At 25 fps, each frame should be
multiples of 40 milliseconds.

To get it in sync I have to use fixpts=fps=25

mplayer -vf framestep=i,fixpts=fps=25,fixpts=print test.avi

I use this information to split AVI videos at the exact frame numbers. In
the past, all I needed was -vf fixpts=print

This bug - if it is a bug - may have started after r34401. Can it be fixed?
