 When installing plugins (from wp interface), they are installed fine, but
 give warning. Example:
 {{{
 Installing Plugin: WordPress Importer 0.6.1
 Successfully installed the plugin WordPress Importer 0.6.1.
 Warning: json_encode() [function.json-encode]: recursion detected in
 /home/USER/public_html/test/wp-includes/update.php on line 261
 Warning: json_encode() [function.json-encode]: recursion detected in
 /home/USER/public_html/test/wp-includes/update.php on line 405
 }}}
 In my installation (3.9-beta3-27857), line  261 in 3.9-beta3-27857:
 {{{
         $url = set_url_scheme( $url, 'https' );
 }}}
 Line 405:
 {{{
         $raw_response = wp_remote_post( $http_url, $options );
 }}}
 Maybe something has to do with ssl? I was logging in on ssl (https) (self-
 signed, if this matters).
 I logged out and re-logged in with plain (http), but the same warnings
 appeared.

 When updating wordpress, I get the same error. As it does not stay for
 long, I took a screenshot for it.

 There is a similar warning for those same php lines in:
 #27633 closed enhancement (fixed) , which is about UPRADING plugins or
 themes.

 Notes:
 Server:PHP 5.2.17, MySQL 5.5.36, Memory Usage 37,193,072 bytes

 Site is right-to-left enabled, Arabic language enabled in wp-config.php,
 but wp language file is not uploaded.
