Parameter 1 to theme_hidden_captcha_captcha() expected to be a reference, value given

I see this error everytime I try to add a hidden captcha to a form.
I had to change

theme_hidden_captcha_captcha(&$element)

to

theme_hidden_captcha_captcha($element)

Don't know if it is the right solution.
Can you confirm this?
Thanks

This is correct, there should not be any & there. I've checked in the fix.

Thank you.
