Wrong submit buttons getting ajaxed

Hello,
After installation i have noticed that for anonymous users only, some forms buttons are being ajaxified.
For example i have a page with two forms loaded (webform & user login). When i submit webform, an ajax request is made with an error.
The error is logged as Invalid form POST data. This is normal as its no supposed to be ajaxed.

Tried this and it worked fine.
In ajax_register.module after line 250 add following two lines:

$form['actions']['login_submit'] = $form['actions']['submit'];
unset($form['actions']['submit']);

Above code will make sure not to attach ajax to similar buttons on other forms.

Any better solutions?
