 This is the first time I create ticket in WordPress Trac. I hope this
 ticket will go well!

 When I call `get_user_meta( $user_id, 'wp_capabilities' )`, My expected
 returning is:
 {{{
 Array(
         [administrator] => 1
 )
 }}}

 But contrary to expectations, it returns `a:1:{s:11:"contributor";b:1;}`.
 (cf: [http://ja.forums.wordpress.org/topic/128564 Japanese Forum Topic])
 As a result of inspection, I found a bug in `is_serialized()` at the
 following  conditional expression:
 {{{
 if ( false !== $semicolon && $semicolon < 3 )
 }}}

 In this case, `a:1:{s:11:"contributor";b:1;}` includes only '''2'''
 semicolons, but this is valid serialized string! So if first argument of
 `is_serialized()`, $data, terminated in `}`, I guess we have to count up
 $semicolon by `++$semicolon;`.
