Commented Unassigned: Syntax Error with var dnnpagesSelectBox [7610]

After upgrading to CKEditor 2.00.07 on DNN 4.9.5 the following error shows up in Firefox 23.01

SyntaxError: missing ; before statement

var dnnpagesSelectBox = new Array);

/Providers/HtmlEditorProviders/CKEditor/ckeditor.js
Line 358

After upgrading to Firefox 24, Firebug now says the same error is coming from a different location:

var dnnpagesSelectBox = new Array);

/Providers/HtmlEditorProviders/CKEditor/Tabs.ashx?PortalID=0
Line 1 col 33

Google Chrome 29 reports this error:

Uncaught SyntaxError: Unexpected token )

var dnnpagesSelectBox = new Array);
