Description:
------------
I have set an error handler to handle E_ALL errors, but i 
still get standard PHP error messages in some instances. 

Reproduce code:
---------------
function debug ($errno, $errstr, $errfile, $errline, $errcontext) {
 print "<pre>";
 print "Error: $errstr";
 $backtrace = debug_backtrace ();
 $first = 1;
 $i = 1;
 foreach ($backtrace as $context) {
  if ($first) {
   $first = 0;
  } else {
   print "\n\t$i: $context[file] line $context[line]  ";
   if ($context['class']) {
    print "(".$context['class']."->".$context['function'].")";
   } elseif ($context['function']) {
    print "(".$context['function'].")";
   }
   $i++;
  }
 }
 print "</pre>"; 
}
set_error_handler ('debug', E_ALL);

Expected result:
----------------
Very verbose debug output such as: 
Error: Use of undefined constant self - assumed 'self' 
        1: /www2/wame.net/system/include/class/dbObject.php 
line 169  (dbObject->cacheData) 
        2: /www2/wame.net/system/include/class/dbObject.php 
line 128  (ProviderRealm->cacheData) 
        3: /www2/wame.net/system/include/class/dbObject.php 
line 240  (ProviderRealm->dbRead) 
        4: /www2/wame.net/system/include/class/dbObject.php 
line 203  (ProviderRealm->dbWrite) 
        5: /www2/wame.net/system/include/class/dbObject.php 
line 203  (Provider->__destruct) 
        6: /www2/wame.net/system/include/class/dbObject.php 
line 203  (Provider->dbWrite) 
        7:  line   (dbObject->__destruct) 

Actual result:
--------------
Note that this is not the same error as above, as this 
error is the one the handler doesn't deal with properly. 
 
Fatal error: Access to undeclared static property:  
dbObject::$_elements
