Fail softer when format text is broken

[sbalmer]

Hi there!

We had some trouble tracking down a broken translation string. Because broken format strings are a common occurrence for us, I'd like to improve error handling. This patch causes mf() to retry in the native language should the translated string fail.

Thanks for having a look at this. I'm not sure this is the best way to go about it, but at least our site won't show [Object object] messages anymore this way :-)

Cheers Stephan
