No, look at the comment above in the code. It is wrong to set labelsOnly to true when loading the layers config for the first time. This sequence:

 1. Load application.
 1. gaTopicChange event. We cannot load the layers config because we don't have a lang yet.
 1. $translateChangeEnd event. We have both a topic and a lang now. Go get the layers config. But in that case we don't want to set labelsOnly to true.
