Airbrake is swallowing build errors and blowing up

[adambedford]

I'm observing that Airbrake is raising an exception trying to parse build errors from Ember CLI:

can't parse '
' (please file an issue so we can fix it: https://github.com/airbrake/airbrake-ruby/issues/new)
can't parse '
' (please file an issue so we can fix it: https://github.com/airbrake/airbrake-ruby/issues/new)

ActionView::Template::Error (:frontend has failed to build:
):

Wondering if anyone has run into this before? FWIW, Airbrake is configured to not send errors in development, but raised exceptions still go through the handler.
