Hi.
Just come across a somewhat strange issue. I wanted to add a search widget with the title "Search the Site". In my widgets panel there was however two available search widgets: the Thematic one and the default Wordpress one (that gave me the possibility to change the title).
The problem is that the title wouldn't save. Also if I added just the Wordpress widget it wouldn't be displayed at all.
Something similar is happening with the Meta widget.
I looked into Thematic and the issue was happening because two lines in the widgets.php file:
unregister_widget_control('search');
unregister_widget_control('meta');
Now... my question is... why do we need to unregister the widget controls for search and meta?
