Hi All
I've found an problem when cropping really large pngs.
I start off with a 14mb, 14468x13523 png. I run it through
convert -crop 14464x13504+0+0 Pre-Crop.png Post-Crop.png
and I get a 2.4mb png which is mostly black, with the odd band of picture.
I've found this with imagemagick 6.0.6 and 6.2.4, both on i386 Linux
The images are available at:

Thanks
Nick
