Description:
------------
I have a very standard session handler I'm writing, with 
the write function as below.

I'm using propel (propel.phpdb.org) as an object 
persistence layer.

When the function is called automatically by the session 
system, the first print statement correctly prints the 
session id.  However, an exception is thrown when the 
record does not yet exist in the database, and the catch 
block in entered.  Here, the second print statement 
incorrectly prints $id, printing instead some path:

Output:

0a900f631d4ebf175f7b85ec262ca7292
/Users/msaffitz/cvswork/aspen-in
Failed to select one and only one row.
/Users/msaffitz/cvswork/aspen-in

Reproduce code:
---------------
 public function write( $id, $val ) { 
    print "$id<br>\n";
    try { 
      $session = SessionsPeer::retrieveByPk($id); 
    }
    catch ( PropelException $exception ) {
      print "$id<br>\n";
      print $exception->getMessage();
      $session = new Sessions();
      $session->setId($id);
    }
    print $id;
    $session->setDatavalue($val);
    $session->setModificationDate('NOW()');
    $session->save();
  }
 

Expected result:
----------------
The variable $id's value should persist.
