New description:

 When encoding to mp3 with FFmpeg 1.1 and the source has cover art it
 always halts with an error.
 When you add -vn it works fine. But then you cannot add coverart yourself.

 Audio packet of size 417 (starting with 1F009064...) is invalid, writing
 it anyway.
 ffmpeg(878,0x7fff7c80e180) malloc: *** error for object 0x103101ee0:
 pointer being freed was not allocated
 *** set a breakpoint in malloc_error_break to debug
 Abort trap: 6

 This issue was not present with FFmpeg 1.01
