This bug report describes a segmentation fault when trying to encode an avi
produced by Canon Digital IXUS v2 to mpeg4. Playing the same file with
mplayer works without problems. If I use -oac copy when encoding, the
segmentation fault does not occur. So this seems to be related to the pcm ->
mp3 encoding.

Similar bug report already reported is in here:
