    Fixed headers_end calculation for incomplete buffers
    
    2012-04-12  Jeffrey Stedfast  <fejj gnome org>
    
    	* gmime/gmime-parser.c (parser_scan_headers): Make sure to
    	initialize 'start' before using it to calculate headers_end in
    	the case where parser_fill() failed.
    
    	Fixes bug #673493.
