As I have nothing for the search_sources and add_source sections,
the addressbook icon does not appear next to email addresses when
viewing messages.
  
If I use the following selection then the icon appears but when I
try to use it I get the error "Invalid addressbook".

// addressbook to use for adding adresseses
$_prefs['add_source'] = array(
    'value' => 'Local SQL',
    'locked' => false,
    'shared' => false,
    'type' => 'implicit'
);


I assume that I am missing something really obvious here :-)

Thanks,
Dominic.
