I have no idea. But I really doubt that at least three different  
people have broken their PHP install in the same way.

I tried, but failed. The below is what is in my /usr/share/php5/PEAR/Horde.php

     73          /* Chicken/egg: we must wait until we have basic  
framework setup
     74           * before we can start logging. Otherwise, queue entries. */
     75          if (Horde_Core_Factory_Logger::available()) {
     76              if (empty($GLOBALS['injector'])) {
     77                  // Horde::debug('WTF???');
     78              } else {
     79                   
$GLOBALS['injector']->getInstance('Horde_Log_Logger')->log($event,  
$priority, $options);
     80              }
     81          } else {
     82              Horde_Core_Factory_Logger::queue($event,  
$priority, $options);
     83          }

If I uncomment the line with Horde::debug, it fails in the same way as  
the version from stock Horde_Core-2.4.2. I really have no idea how to  
force a backtrace here. It makes no difference if I use

     76              if (empty($GLOBALS['injector'])) {
or
     76              if (!is_object($GLOBALS['injector'])) {

In both cases a blank page is shown if I open the addressbook and  
leave the Horde::debug line uncommented.
