22354	Gravatar Shouldn't Use images/blank.gif	miqrogroove	nacin	"There is a very subtle flow-of-control error in pluggable.php:

{{{
	elseif ( 'blank' == $default )
		$default = includes_url('images/blank.gif');
}}}

This makes sense when $email has no value, because it will cause the local blank.gif file to be displayed.  However...

When $email is not empty, this function is causing the gravatar.com server to make a proxy request to the blank.gif file and display the local file through a remote request.  This is not the intended behavior.  When the $email value is present, the Gravatar request should simply contain ""&d=blank"" to get a blank image."	defect (bug)	closed	normal	3.5	General	3.4.2	normal	fixed	has-patch
