 I get the crash with attached file under win32

 under amigaos i got in the past this:

 {{{
 Stream #0.0: Video: mpeg2video, yuv444p, 512x512 [PAR 1:1 DAR 1:1], 6000
 kb/s, 30 fps, 30 tbr, 1200k tbn, 60 tbc
 }}}

 but now I get:

 {{{
 Stream #0.0: Video: mpeg2video (), yuv444p, 512x512 [PAR 1:1 DAR 1:1],
 6000 kb/s, 30 fps, 30 tbr, 1200k tbn, 60 tbc
 }}}

 so maybe crash in strlen() make sense? (this is libav debug build btw,
 because I can't find debug ffmpeg)

 if this is reproductible with the head I will try to find rev when
 regression happened
