After Bug 19791 was implemented, it was discovered that the comment field has substitution methods. Because of this, any % in the input text has to be escaped to %% See also ImageMagick documentation on properties http://www.imagemagick.org/script/escape.php?ImageMagick=i766ho1om315scce8eh75efjc6
Fixed in r64932, r64932 and r64935
