token_form_block_admin_configure_alter() contains the line:
$form['settings']['title']['#token_types'] = array();
this is to prevent you from using a token that might not be replaced when the block is displayed. However, another module may already have a dependency on certain token types and want to display that token where possible (for example, cck_blocks can only be used on node pages, so setting $...['token_types'] = array('node'); is both safe and useful).
If $form['settings']['title']['#token_types'] has already been set by such a module, then we should not overwrite that value. Patch to follow.
