TypeError: Cannot read property 'email'/'password' of undefined

I have found the `{{atNavButton}}' mentioned in the documentation, and I hought "Great! I don't have to bother with this!" but using the template generate these errors :

Exception from Tracker afterFlush function:
TypeError: Cannot read property 'email' of undefined

Might this be the same as #367?
...actually it might be you're using the nav button without the signIn route configured and you end up redirected to an unexisting route.

Please make sure you have at least one call to

AccountsTemplates.configureRoute('signIn`);

or similar.

This should now be solved with v1.12.3 and the new useraccounts:iron-routing package...
