[turba] CardDAV error.

[David Verdin]

Dear all,
I'm using Horde since a few years with great pleasure.
I use the CardDAV functionnality to keep sync between my computer and my 
phone.

I recently completed the nightmare-ish upgrade from Ubuntu 14.04 to 
16.04. that means I upgrade to PHP 7 and Imoved from Turba4.1.3 to 4.2.12.

Everything seemed fine BUT cardDAV does not seem to be working anymore.
The steps to reproduce:

1- access the CardDAV subscription ULR : 
https:/<domain.tld>/horde/rpc.php/addressbooks/<username>/contacts:<key>/

What happens:

The following error is returned:

<d:error>
     <s:exception>Sabre\DAV\Exception</s:exception>
     <s:message>Server error when performing search.</s:message>
     <s:sabredav-version>1.8.12</s:sabredav-version>
</d:error>

In the logs, I can read:

"/usr/share/php/Horde/Db/Adapter/Pdo/Base.php"]

I checked the database and did not find any table called "turba_objects".

The database schema is supposed to be up-to-date as well as the 
configuration as per what the web administration interface tells me 
-though I can't update horde config, it raises an uncaught exception, 
but that must be unrelated.
CalDAV (on Kronolith) is working perfectly.
Access to the Address book through the web interface works well too.

Do you have any clue about how to get out of this situation? I'm quite 
stuck here...

Best regards,
