Subject: ffmpeg segfault png to ogg conversion
Package: ffmpeg
Version: 3:0.svn20090303-1
Severity: normal

ffmpeg crashes every time when attempting to convert some png files to ogg files. The files were generated from scilab EPS output using imagemagick with convert EPSFILE -depth 8 PNGFILE. The sequence seems to crash somewhere in libgtheora after a given number of png files. Each file is individually openable in gqview. 

I have provided a link to a script (with png files) which shows this behaviour.
