Please describe the actual behaviour

If the portal is in Bootstrap 2 mode, the "New view" button located in the "Views" tab for a resource, when clicked it does not give a list of possible views to create. Instead in the browser console it shows the following error when clicked:

jquery.min.js:2 Uncaught Error: Syntax error, unrecognized expression: #
    at Function.ga.error (jquery.min.js:2)
    at ga.tokenize (jquery.min.js:2)
    at ga.select (jquery.min.js:2)
    at Function.ga [as find] (jquery.min.js:2)
    at r.fn.init.find (jquery.min.js:2)
    at new r.fn.init (jquery.min.js:2)

    at HTMLAnchorElement.toggle (jquery.fileupload.min.js:6)
    at HTMLDocument.dispatch (jquery.min.js:3)

What steps can be taken to reproduce the issue?

In a CKAN 2.8 portal, make it to use Bootstrap 2 by setting ckan.base_templates_folder to templates-bs2 and ckan.base_public_folder to public-bs2 in the config file. Then create a resource. Go to the "Manage" page for the created resource and then "Views" tab. Try to click the "New view" button.
