Description:
------------
When open TIFF images created with Adobe Photoshop there are some warnings reported by ImageMagick library (such as "unknown tag"). When file opened with ImageMagick libraries (convert etc) program execution continues as normal, but when PHP function imagick_readimage is called on these TIFF image then error reported and null handle returned. It's no good.
My solution is simple comment out source code in imagick.c (line 5534):

        if ( _php_imagick_is_error( handle ) )
        {
                _php_imagick_clean_up_handle( handle ) ;
                return NULL ;
        }

Will be very pleasant if you can do such thing in your package because of my depression patching every new version of PHP.
