Created attachment 8559 [details] Screen Shot of Error With older versions of ImageMagic (not sure which all, but tested with 6.0.7), the thumbnails of newly uploaded images are simply the text "Error creating thumbnail: convert: unrecognized option `-set'." on a gray background (see attachment).
Created attachment 8560 [details] Patch Broke in r60175 (version 1.15.2 and higher).
ImageMagick 6.2 (maybe even 6.3) is our minimum requirement I believe. I do not see this as a bug. You should not use ImageMagick from 2004: http://sourceforge.net/projects/imagemagick/files/old-sources/6.x/ it's full of security holes and the commandline syntax has changed so much since then, it's not worth being compatible with old versions and running the risk of not being compatible with future versions.
According to a comment in Bitmap.php, it's now 6.5.6-2 (as of 1.18). 283 // JPEG decoder hint to reduce memory, available since IM 6.5.6-2 284 $decoderHint = "-define jpeg:size={$params['physicalDimensions']}";
