There is a problem setting these after constructing the widget, because of the 
G_PARAM_CONSTRUCT_ONLY attribute on the property.

So I get this at runtime : 
GLib-GObject-WARNING **: IA__g_object_set_valist: construct property "tile-cache-base" for 
object `OsmGpsMap' can't be set after construction
