    plug-ins: tiff-load initialize a variable before using it
    
    Initialize channel[0].buffer before using it, as a response to the following
    critical warning reported in issue #3264 about it being NULL:
    
    (file-tiff:1074): GEGL-CRITICAL **: 17:10:57.175: gegl_buffer_get_format: assertion 'buffer' failed
