[turba] Unable to delete contacts from Personal Address Book, no errors.

[Adam Tauno Williams]

Horde: 3.1.1 Turba: H3 (2.1.1) PHP: 5.0.4 Apache: 2.2.0-21

When deleting a contact from my "Personal Address Book" which is the
standard Turba table in a PostgreSQL 8.x database the contact is not
deleted; I'm bounced to the browse.php page and presented with a "There
are no browseable address books." message.

I have both PHP and Horde logging enabled.

Horde reports -

 ... These queries go on for awhile, but all look the same.
 - during this option and the PHP log reports nothing.

PHP error logging configuration is:
log_errors = On
error_log = /srv/www/htdocs/phperrors.log
error_reporting = E_ERROR | E_WARNING | E_PARSE | E_NOTICE |
E_USER_ERROR | E_USER_WARNING
warn_plus_overloading = true
display_errors = false

I can create and update contacts without incident.  I tried adding a new
contact and deleting it immediately and that failed as well.  Updating
that contact worked.
