[horde] Cannot save preferences [they just disappear]

[Adam Tauno Williams]

Horde 4.0.14

I'm attempting to put together an install of the latest Horde  
packages.  Horde is "running" just fine.  Adminsitration says all the  
databases are current.

But I cannot save preferences.  The "save" completes, I even see the  
INSERTs performed in the log ...

INSERT INTO horde_prefs (pref_uid, pref_scope, pref_name, pref_value)
	  VALUES('adam', 'horde', 'identities',
	  E'\\x613a313a7b693a303b613a31373a7b733a31363a2264656661756c745f6964656
	  e74697479223b693a303b733a393a2266726f6d5f61646472223b733a32313a2261646

   **BUT*** if I log out and then back in the preferences are lost; or  
at least no loaded.

I found <http://bugs.horde.org/ticket/10919> which i thought might be  
related but performing a "ALTER DATABASE horde SET bytea_output =  
'escape';" didn't effect the issue.

I don't see any log messages indicated there are errors  
*loading/reading* the preferences from the back-end [the same  
PostgreSQL database Horde uses overall].

Any pointers would be appreciated.
