I experience problems with export of my workouts to XML Since 15 August 2009. It applies to both new and earlier workouts. Before, the exports of all workouts were correct, so I believe the problem isn't in the GPS device (Nokia by the way :-)).

The workout starts with many "zero" records, then one record thousands kilometers away of the actual workout, then correct points of the route.

Sample workout from 2008-03-01: http://sportstracker.nokia.com/nts/workoutgraph/workoutservice.do?id=91684

1) Many zero points
