--------------------------+-------------------------------------------------
 When register_sidebar_widget is called with a lambda/create_function as
 output_callback and no/empty classname, the widget's CSS class will
 contain "\0lamba_123" (\0 being the null character and 123 being the
 actual assigned lamba id).

 This bug was introduced in 2.3 by #4910 (In [6098]).

 The simple fix might be to left-trim null bytes from the classname (this
 would fix the case for lambda's, and maybe other cases I'm not aware of)
