Looking at your var_dump, it looks like you have an enormous amount of 
address books. This leads me to believe there might be something wrong 
with your share configuration. Or perhaps a botched upgrade at some 
point in the past?

ah well ... still can't reproduce this though.

No, this was a different issue.

jan, would this have been fixed by your recent turba contact list commits?

Yes, it works

Does this address book otherwise work normally?

I´m sorry about the delay, but I had some problems.
Here is the begining (the results are enormous - I attached a pdf with 
everything) of the var_dump($targetdriver) results:

..what about the results of the var_dump() statement?

I'm using mysql and the beginning of sources.php is:

$cfgSources['localsql'] = array(
     'title' => _("My Address Book"),
     'type' => 'sql',
     // The default connection details are pulled from the Horde-wide SQL
     // connection configuration.
//    'params' => array_merge($GLOBALS['conf']['sql'], array('table' 
=> 'turba_objects')),
      'params' => array(
          'phptype' => 'mysql',
          'hostspec' => 'localhost',
          'username' => 'horde',
          'password' => 'senha',
          'database' => 'localsql',
          'table' => 'turba_objects',
          'charset' => 'iso-8859-1'
     ),

I cannot reproduce this is the latest stable. What contact storage 
backend are you using?  You are probably going to need to debug this 
yourself.

Find out what line you are *now* getting the error on (after you 
upgraded, the line number will have changed).  Place a   
var_dump($targetDriver); statement right before the line you are 
getting the error on and post the results here after making sure no 
sensitive data (data base passwords etc...) are present.

Thank you for your response
I have updated turba to the newest version and the error persists.
I'm creating the new list in the same address book as the contacts.

That error would be caused when the driver for the address book you 
are creating the new contact list in could not be loaded.  Are you 
creating the new list in the same address book as the contacts, or a 
different address book?

Also, 2.2.1 is an older release. Please update to a newer version, as 
this issue may have already been fixed. I cannot reproduce this in the 
current stable line.

I installed Imp 4.2/Horde 3.2.1/Turba 2.2.1 on Fedora core 11. Everything is
working fine except the option "add " option to create a new list.

    I select the contacts I want to add and then select "add" option to
My address book. Turba asks me the name of the new list. I type the
list name and click ok. A blank screen appears and nothing happens.

    I found an error in ssl_error_log:

    [Thu Feb 11 08:56:25 2010] [error] [client 192.168.0.227] PHP Fatal

    Thank you for any help!
