Title:
  ffmpeg crashed with SIGSEGV in av_image_copy()

Status in libav package in Ubuntu:
  Incomplete

Bug description:
  i tried to convert an audiobook (.m4b with png-pictures [vfr], aac-sound, and chapters) into mkv. The crash is easily reproducible, no matter what target-codecs are being used. But the same conversation succeeded with ffmpeg in Natty (don't know the version-number as i have no natty-pc here at the moment). I am using a VirtualMachine under VirtualBox 4.1.4 r74291
  A Sample of the AudioBook i've used can be freely downloaded under http://download.jw.org/files/media_books/we_X.m4b
