[Plugin: Debug Bar] javascript error in version 0.4.1

After updating the debug bar, the debug menu does not work anymore.
I get a notice of a javascript error

<strong>g is null</strong>
(function(){var d,b,a,c;d=function(g,f...);d(e,"click",a);d(f,"click",c)})})();

Clicking on the debug menu reloads the page.
