Seems Galilieo is not listening for "GPS online again" event or something.
Started Galileo (and start track recording) and Runkeeper, then pushed 'Home' and no app was in focus. Walked a few km, then into a store. Checked the phone and both apps had kept track; pushed 'Home' and no app was in focus again. Inside the store, GPS lost track of satellites. 30 min later I walked outside and home again, but when I came home Galileo had not registered that the GPS came "online" again (Runkeeper did this though), so the whole way home became a long straight line from where it lost track to where I checked it at home again.
