As far as I understand KP, it looks like the data we get from the server is slightly corrupted. In particular, for vegan and vegetarian, the elements refer to a panel that does not exists in the rest of the JSON ("ingredients_analysis_help"). And that's the reason of the crash: a null panel where we expect one.

Is there something we're missing in Smoothie's parameters that prevents us from getting the "ingredients_analysis_help" panel? I don't know. Anyway, we could play it robust and take into consideration the possibility of a null panel without crashing. About to PR...
