I've seen (unanswered) crash reports related to ImageMagick. Eg http://debbugs.gnu.org/cgi/bugreport.cgi?bug=8341 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11701 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11831 And as you know, ImageMagick support for animated/multi-frame images is broken http://debbugs.gnu.org/cgi/bugreport.cgi?bug=7978 And likewise for metadata in general http://debbugs.gnu.org/cgi/pkgreport.cgi?include=subject%3Amagick;package=emacs And no-one seems interested in working on any of these issues, so IMO we should stick with the more tested image libraries as default for the formats that they handle.
