Missing session leads to Javascript-Error

If you press F5 in a non-development installation, you get logged out.

This is by purpose and good.

But in many cases the browser reloads the application and the loading of the extjs-resources of translate5 starts.

Then translate5 loads the json-Data from the server and gets some HTML, because the user is not logged in.

This leads to errors like this one here:

Can you please solve this in such a way, that the user is redirected to the log-in page, if no session exists instead of translate5 throwing an error?
