My guess, and probably something others have done as well, is as follows:

1. Someone wants to change default value of pref (we'll use reply_lang  
as example).
2. They copy/paste the entry from prefs.php:

$_prefs['reply_lang'] = array(
     // 'value' => serialize(array())
     'value' => 'a:0:{}',
     'advanced' => true,
     'type' => 'multienum',
     'enum' => array(),
     'desc' => _("What language(s) do you prefer replies to your  
messages to be in? (Hold down the CTRL key when clicking to add  
multiple languages)"),
     'on_init' => function($ui) {
         $enum = Horde_Nls::getLanguageISO();
         asort($enum);
         $ui->prefs['reply_lang']['enum'] = $enum;
     },
);

to their prefs.local.php.
3. They delete everything but the value they want to change:
$_prefs['reply_lang'] = array(
     'value' => 'a:0:{}'
);

The problem now is that all the other properties of reply_lang have  
been deleted.

The proper way to set the value in prefs.local.php is as follows:
$_prefs['reply_lang']['value'] = 'a:0:{}';

This only overwrites the 'value' property of reply_lang, not the entire array.
