When unioning shapefiles in QGIS, the process gets to about 6% and finishes, leaving a layer that is unioned correctly but has missing polygons. I have tested this with multiple files and it fails each time, it does not appear to be a coordinate system issue. When it did not work in 1.7.1 I installed 1.6.0 and tried the same process, which yielded the same error. Moreover, all other geoprocessing ftools work correctly, so it appears to be an issue with this particular tool.

I have tried installing as an administrator, as I understand that not doing so often causes problems, but that solves nothing.

Whatever the problem is it leads to data corruption, so I consider it a high priority fix.
