 * Hello everybody,
    editing a post on a WP installation of mine, i came across 
   this never-had-before problem: ` PHP Catchable fatal error: Object of class stdClass
   could not be converted to string in /path/to/myWP.blog/wp-content/db.php on line
   601, referer: [...]/wp-admin/post.php?action=edit&post=787&message=1  Probably
   some plugin with some post enahnacement function (like a calendar plugin) has
   triggered this WP bug; the problem is similar to others, like [this one](http://core.trac.wordpress.org/ticket/9640):
   when WP tries to escape data before insert them in the database, it checks only
   for arrays and strings (99% times it is enough) and not for objects. I’ve posted
   this on discussions about “DB Cache Reloaded” cause I’m using it on that blog
   and the bug above was founded on wp-db.php (core WP library) and obviously on
   the db.php created by this plugin that, if I’m not wrong, replicate (or extends,
   don’t know) part of the WP core db library.
 * So i’ve patched the “escape” function on theese two files and on the source file
   in “DB Cache Reloaded” (db-module.php), this way:
 *     ```
       function escape($data) {
         //PATCH START
         if(is_object($data))
           $data = serialize($data);
         //PATCH END
         if ( is_array($data) ) {
           foreach ( (array) $data as $k => $v ) {
             if ( is_array($v) )
               $data[$k] = $this->escape( $v );
             else
               $data[$k] = $this->_weak_escape( $v );
           }
         } else {
           $data = $this->_weak_escape( $data );
         }
         return $data;
       }
       ```
   
 * and it seems to work for now. I Hope sirzooro (and others of course) can help
   me analyze and resolve this issue the right way.
