Travis: Initiating build for commit '2034818e88e6024894c09acc9ad8f8cecafe19fb': Fixes #4149 Quick fix by ignoring the URL that failed to insert. To properly fix one can change the collatoin on the site_url table to use German collation in mysql 5.5 (maybe other collations would work too see mysql bug http://bugs.mysql.com/bug.php?id=57860 )
