nit:  These all should be using two space indent.

Can't you just use:

if (errorPageController) {
  errorPageController.blah();
}

Done.

When I disable the Gin bindings (to mimc IOS) and try that, I get:

[14801:14801:0415/142343:INFO:CONSOLE(386)] "Uncaught ReferenceError:
errorPageController is not defined", source: data:text/html,chromewebdata (386)

Ah, right.  "window.errorPageController" would work, though - I prefer it for
being more C-like, and I don't think we care about the case where it has a value
of null, false, 0, or the empty string.  But I don't feel strongly about it.

Huh.  Learn something new every day; thank you.  Done.
