Gets me a correct exception.

when i create a sample test case:

<?php
throw new ErrorException("hallo");
?>

i got:


PHP Fatal error:  Uncaught exception 'ErrorException' with message 
'hallo' in -:2
Stack trace:
#0 {main}
   thrown in - on line 2


but when it is called inside horde the class can't be found like in my 
error message. perhaps you can test my testcase to see the actual 
result. the permission i set wrong was file owned by root:root and 
only had read permission for user and group when my webserver is 
running with user www-data:www-data

Your PHP is broken.  ErrorException is part of PHP itself:

http://php.net/ErrorException

when i have set a wrong permission on my backends.local.php so that it 
is not readable for the webserver i got a fatal error about that class 
ErrorException can't be found:
  PHP Fatal error:  Class 'ErrorException' not found in 
/var/www/pear/php/Horde.php on line 238

so i searched the entire horde installation for that class and didn't 
found it, but i found some places where it is thrown, so eighter the 
file is missing in some place or the throws are false.


  grep -R ErrorException /var/www/pear/php | grep -v registry

ErrorException('PHP ERROR: ' . $errstr, 0, $errno, $errfile, 
$errline), $priority);
/var/www/pear/php/Horde/Mime/Part.php:                } catch 
(ErrorException $e) {
