Unsolved Ugly expired session page

[JohanSolo]

Hello,

any time my 14 days sessions expires, I get this ugly error page:

{"code":"not-authorised","message":"A valid login session was not found. Please log in and try again.","params":{}}

If you ask how I get to this page, it's simply that my browsers simply reload my previous tabs and I always have a tab with unread messages from Qt forums.

Now, since obviously the expiration of my session is detected, why not redirecting me directly on the login page? I've experienced this with FF on both windows and linux, and chrome on windows.
