Thanks for the report. Removed the type hint, should be fixed.

Changes have been made in Git for this ticket:

Remove type hint as Horde_Core_Share_Driver does not declare that it 
implements Horde_Share_Base (Bug #10493).

Wrobel       Add a new handler for task lists.

I have this fatal error:
PHP Catchable fatal error:  Argument 1 passed to 
Nag_Tasklists_Default::__construct() must be an instance
of Horde_Share_Base, instance of Horde_Core_Share_Driver given,
called in   
/disc2/gits/jpdev.webmail.labs.sapo.pt/webmail/nag/lib/Factory/Tasklists.php 
on line 65 and
defined in 
/disc2/gits/jpdev.webmail.labs.sapo.pt/webmail/nag/lib/Tasklists/Default.php 
on line 28

I have made this fix, but dont know if is the correct solution.
