Starting Gmail without Labs features enabledEdit

I have a few Gmail accounts and suddenly this morning one of them started refusing to load. This wasn’t browser-specific (tried it in multiple browsers), and my other accounts loaded just fine.

You can prevent Labs features from loading by supplying labs=0 as a query string parameter; for example I changed:

  •; to:

And now Gmail loads again, as does the "basic" view.

I’m not actually sure what the problem is, as it reappears on switching Labs features back on.
