Because of this line at the bottom of imp/lib/prefs.php:

// Don't show Trash options if Trash is disabled.
if (!$GLOBALS['prefs']->getValue('use_trash')) {
     $GLOBALS['_prefs']['trashselect']['type'] =  
$GLOBALS['_prefs']['use_vtrash']['type'] =  
$GLOBALS['_prefs']['empty_trash_menu']['type'] = 'implicit';
}

And the check on use_trash that won't let you turn it on if there is  
no trash folder, it is impossible to turn on use_trash if you haven't  
previously selected a trash folder, and you can't select a trahs  
folder because that selection is hidden when use_trash is off.

I *think* the thing to do here would be to just always show the  
trashselect pref and go from there. Any other ideas?
