Hi,

    This happens when the original file have a incongruent PNG Class.

    Will be very long to explain how to solve.

    The most immediate solution I can tell you is that your image must 
be PNG: PseudoClass, not "DirectClass"

    Start from: syslogo.png and use "display" from ImageMagick tools/library
