This question reminds me about similar problem with non-relevant menu items. 
You can either hide the item or disable it. AFAIK the current answer is 
"disable".

What if we try the same approach here?

We could grey out this "clear" button when there's no text and disable onclick 
for it. This would solve the first problem Aaron listed.

We could also make it as light grey as possible to cut down visual noise to 
solve the second problem.
