Start Debug causes exception in jquery before actual page is loaded

I just press debug for a page and even before the first script in the page is loaded the WebStorms debugger halt in

"chrome-extension:\\jeoacafpbcihiomhlakheieifhpjdfeo\scripts\vendor\jquery\jquery.js"

Here is the stack trace:

Error: Failed to execute 'querySelectorAll' on 'Element': '*,:x' is not a valid selector.

Would be great if anyone has an idea.
