Distance Matrix entries are only calculated for the first feature

Description

To reproduce, you can simple use the airport.shp dataset from the QGIS sample data. Try to calculate distance matrix. The resulting distance matrix text file only contains entries for the first feature.

I've attached a screenshot too.

This tool used to work correctly in 1.8, so this is a regression.

The issue is back in nightly. Only the distances from the first point to all other points are calculated.
Additionally, when the script is finished, one point gets selected. So if you rerun the script without noticing, the result will then only have one line (because only selected points are used by processing).
