 Summary of the bug: shortest command doesn't work when using a
 filter_complex with audio and video filters

 I uploaded output.mp4 at 8:21 ET on 7/20/14 to upload.ffmpeg.org

 The background audio is 4 mins long, but it should be truncated to the
 video length.

 Shortest works if I take the drawtext off the filter_complex

 How to reproduce:

 ffmpeg -framerate 1/5 -i foo%03d.png -i audio.wav -i speak.wav
 -filter_complex
