I have to add that the input boundary *has to* be a single line already (ie. 1
boundary with 2 snapped nodes) for the bug to pop up. Such a line is the
'parcel' vector from the location available at
http://www.biol.uni.wroc.pl/sieczka/udostepnione/grass/poly/poly.tar.bz2.

If v.build.polylines is run on a boundary that is consisted of more than 2
nodes it will work fine though.

The bug is still there.
