The issue with incomplete or empty exports is possibly similar to bug #534679 “Cairo-based export not exporting all elements”: "corrupt" data (e.g. objects with "impossible" geometry/path data/transforms) can cause the rendering to be stopped ("rendering up to, but not including, the first element which has an error") in cairo-based exports.
