AJAX problem in CiviCase - Administer Case Types

Question

I'm getting the same effect as reported here. I'm trying to set up CiviCase, and all seems fine except when I try to Administer->CiviCase->Case Types I just get blank screen. The JavaScript console shows a series of errors as shown below. I've been through all the standard trouble-shooting things, and am stumped now.

Joomla 3.3.6, CiviCrm 4.6.5

Any ideas much appreciated. Thanks.

Javascript console output:

OK, I found the problem. It was the same issue as reported here. It wasn't a CiviCRM problem at all. The JavaScript errors were caused by the K2 component, which alters the HTML output after CiviCRM does. K2 was passing text containing quotes (specifically 'prefix="og: http://ogp.me/ns#"') to JavaScript, so these quotes ended up unescaped. More info here. The solution was to apply this patch to K2 (or, in my case, to remove K2 altogether, since we decided not to use it).
