L.control.locate is not a function
Make sure that you have the
fitBounds() on a layer sometimes breaks/freezes the map in Leaflet 0.7.2
Looks like this bug will be fixed in 0.7.3, a workaround is to invalidate the size of the map before fitting the bounds with
map.invalidateSize() - I guess this bug occurs if the map has not been rendered by the browser yet.
