More likely it is either a incomplete PNG file, or a problem with size limits for the PBM image formats.

We tried the following commands under Fedora using ImageMagick 6.2.6:
  • convert logo: -resize 4651x8567! logo.png
    convert logo.png logo.pgm
and the resulting image was fine (no unexpected black areas).
