Symptom: Horde configuration editor,  
http://localhost/admin/config/config.php?app=<anything>, gives white  
screen until web server restarted.

Reproducing: This cannot be reproduced with 100% reliability, but I  
can cause it with very high probability with the following steps.
1. Restart web server
2. Go to Horde config
3. Go to Imp
4. Go to Kronolith
5. Return to Horde config
6. Reload page about 5 times

Relevant logs: syslog,

Cause: Appears to be the same root problem and solution described at  
http://pyd.io/f/topic/failed-to-load-external-entity-boot-confmanifest-xml/page/3/#post-72211

Solution: Add call to libxml_disable_entity_loader(false) before  
loading conf.xml in /usr/share/pear/Horde/Config.php (see patch).

Environment: Horde 5.1.5, php 5.3.3, libxml2 2.7.6.
