I got this fatal PHP error today:

Message PDOException: SQLSTATE[22001]: String data, right truncated: 1406 Data too long for column 'url' at row 1: INSERT INTO {relatedlinks} (nid, url, title, type) VALUES (:nid, :url, :title, :type); Array ( [:nid] => 2546 [:url] => https://www.google.com/search?q=site%3Agov.on.ca#sclient=psy-ab&hl=en&q=site%3Adigitalontario.mgs.gov.on.ca++OR+site%3Atvo.org+OR+site%3Aocwa.com+OR+site%3Aontarioplace.com+OR+site%3Apowerauthority.on.ca+OR+site%3Ahrto.ca+OR+site%3Aflsc.gov.on.ca++OR+site%3Aohrc.on.ca&oq=site:digitalontario.mgs.gov.on.ca++OR+site%3Atvo.org+OR+site%3Aocwa.com+OR+site%3Aontarioplace.com+OR+site%3Apowerauthority.on.ca+OR+site%3Ahrto.ca+OR+site%3Aflsc.gov.on.ca++OR+site%3Aohrc.on.ca&fp=9c3ac7a173cd3bd7 [:title] => 115k [:type] => 1 ) in _relatedlinks_add_links() (line 539 of /DRUPAL7/sites/all/modules/contrib/relatedlinks/relatedlinks.module).

There are definitely problems with the URL, but there should be some error checking in the module before it gets to the DB. Links should not give fatal errors no matter how long they are.
