Please ignore my earlier comment. Problem still persist.
Here is the similar problem someone else is facing with IE, I am facing with Safari. When I open developer tools on safari there is no error, but if I load the page without developer tools than it fails. looks like Kendo embedded Scripts has somewhere has a dependency of console window.
I am Still working on writing up a sample project to share. If a video cast or screen share is a option, I prefer to setup a time with you to troubleshoot it.
