Comment (by csixty4):

 Thanks for taking the time to report this! However, I can't reproduce it.
 I wonder if there's some kind of multibyte character encoding issue.

 Do you have PHP's locale set to Japan or something other than en_US?

 Test code:

 {{{
 add_action('init', 'check_is_serialized');
 function check_is_serialized() {
         echo (true === is_serialized('a:1:{s:11:"contributor";b:1;}')) ?
 'true' : 'false';die();
 }
 }}}

 When we narrow down the exact cause, there should probably be a unit test
 case added to test_is_serialized() in tests/phpunit/tests/functions.php
