There exists a fork of ImageMagick, called GraphicsMagick. It is currently in version 1.1.10 and was forked from ImageMagick 5.5.2. They strive for higher stability of API and UI.
Steps to Reproduce:
*** This bug has been marked as a duplicate of bug 190372 ***
Could it be that the BugZilla search is broken?
I ran http://bugs.gentoo.org/buglist.cgi?query_format=specific&order=relevance+desc&bug_status=__open__&product=&content=graphicsmagick
and at least if I am not blind, it doesn't show up there...
When searching for duplicate bugs, closed bugs or using multiple search terms, prefix your entry with 'ALL' (not suffix).
Sorry... Last time I tried this never returned anything, so I started using http://bugs.gentoo.org/query.cgi instead. Will switch my behaviour back now.
