The original fix for CVE-2013-6045 disabled decoding of chroma-subsampled images (bug 1093379). OpenJPEG 1.5.2 fixes the vulnerability in a way that doesn't disable that feature (https://bugs.debian.org/734238, messages 48, 53, and 60). However, mingw-openjpeg 1.5.2 is still applying part of the original patch in rhbz1036495_CVE-2013-6045.patch, thus disabling decoding of these images, even though it is not needed on OpenJPEG > 1.5.1.
The OpenJPEG 1.5.2 NEWS file (not included in the release tarball for some reason) also documents that -6045 has been fixed: http://openjpeg.googlecode.com/svn/tags/version.1.5.2/NEWS
