Hi,
there is something wrong with imagemagick (/usr/local/apps/imagemagick) that installed at your server side.
my suggestion please using imagemagick that running under PHP (as php module) instead of imagemagick under server operating system.
there is 2 types of imagemagick.
you can asking your server support to installing imagemagick module at PHP. after installed, you can put empty value for "Caminho do ImageMagick (opcional)" at jomsocial photo settings.
Regards
