I am getting some odd warning message from processing of png to grayscale. Are these to be ignored or significant? Can or should they be suppressed?


convert logo: -colorspace gray logog.png
convert logog.png -negate logogn.png
incorrect gamma=(0/100000)
convert: Ignoring incorrect gAMA value when sRGB is also present `logog.png' @ warning/png.c/MagickPNGWarningHandler/1754.

The logo image include a sRGB color profile. We need to remove the profile when the colorspace is converted to grayscale. We'll get a patch into ImageMagick 6.7.8-1 Beta by sometime tomorrow.
