Undefined array key 1 in class-response.php on line 203

I'm seeing lots of error log entries with:

PHP Warning: Undefined array key 1 in /home/blog/wp-content/plugins/webmention/includes/class-response.php on line 203

wordpress-webmention/includes/class-response.php

Line 203 in 216b1b9

$item[ trim( $elements[0] ) ] = trim( $elements[1], '"\'' );

Appears to be part of get_header_links() - but I don't fully understand what the function does.

@edent do you maybe have an example URL that causes this error?
