Yes, that's the problem.

I think awk might have troubles too. does this give "0,6":
echo "0,3 0,3" | awk '{printf "%.8f\n", ($1 + $2)}'
?


We can't assume "bc" or "dc" are installed, but come to think of it we
are using an arbitrary buffer distance here anyway so it doesn't really
matter if we are +/- 1m. I've just applied a fix in CVS removing the
above "awk" step. please test.
