 Summary of the bug:
 Converting animated GIF to a format other that MP4 cuts the last frame (at
 least).

 The sample GIF has the last frame's duration of 10370ms, totaling ~0:25.
 The resulting video is ~0:15.
 Reproduced for AVI and MKV; other formats probably affected, too.
 Likely related to #4235.

 How to reproduce:
 {{{
 % ffmpeg.exe -y -i sample.gif -c:v mpeg4 videoout.avi
 ffmpeg version N-78758-g5156578
 built with gcc 5.3.0 (GCC)
 }}}
 Also reproduced on ffmpeg version N-80901-gfebc862 built with gcc 4.8
 (Ubuntu 4.8.4-2ubuntu1~14.04.3) (http://superuser.com/q/1153435/106224)
