ImageMagick had been always built using JPEG2000 support ("JPEG-2000 --with-jp2=yes yes"). Since Vivid Vervet's 8:6.8.9.9-5 version it's not more built with jp2 support thus it lost the support to work with JPEG2000 images ("JPEG-2000 --with-jp2=").
This is pretty annoying, as JPEG 2000 is pretty popular lossless format.
