 If you put a single zero 0 in default widgets, it won't output any thing.
 You can try putting a 0 in any widget title or content. It works if you
 put 00 or anything else.

 The reason being our use of `empty( $variable )` and `! empty( $variable
 )` in the default widgets. `empty` returns FALSE if var exists and has a
 non-empty, non-zero value.

 So it will be better to use `isset( $variable) && $variable != ''`
 instead. Wanted to submit a patch but wanted to know if above method will
 be the best one.
