Paolo,

The selection by location algorithm is not the same - it selects features
in one layer that intersect with another layer. I want to join the
attribute tables of two layers where they intersect. Multiple intersections
should either take the first feature, or calculate summary statistics (e.g.
sum, median).

Thanks for pointing out the bug tracker - I probably should have gone there
in the first instance...
