Post any defects you find in the released or beta versions of the ImageMagick software here. Include the ImageMagick version, OS, and any command-line required to reproduce the problem. Got a patch for a bug? Post it here.
I just downloaded and built ImageMagick-6.3.5-8.tar.gz dated Sep 04 00:00 on Ubuntu Feisty x86_64 GNU/Linux and (just for the hell of it), ran make check.

All is fine. Some algorithms permit slight variations in the final result and we account for that with a fuzzy quality check. For your case we adjusted the sensitivity in the regression tests so the next release will pass on your system.
