[FFmpeg-user] Mystery error initializing complex filters -- bug?

Hi All,

A little help, please.

Using the latest git source, using '-filter_complex_script', I get a mystery error.

I have checked the filter_complex_script: 23fps.ffmpeg.filter.txt, for errors. Especially I've 
checked that every input pad (especially [AA1]) has one and only one matching output pad, and that 
every output pad (especially [AA1]) has one and only one matching input pad.

Can you suggest any other checks or should I file a bug now?

Thanks Much!
Mark.
