assertion in void h264_model::update_state_for_model_key when recoding

[sokoow]

I keep getting these:

recode: recode.cpp:1033: void h264_model::update_state_for_model_key(int, model_key): Assertion `symbol == (num_nonzeros == nonzeros_observed)' failed.
Aborted

when recoding x264 video, what is that ?

That means there's a bug in our state tracking. If you can post your video somewhere we can have a look. This library is in a rather early state, so we're still working out the basics.
