Yes. It is excellent information. (but no solution yet)
v.build.polylines in=ditch_1205 out=ditch_1205_single
v.buffer ditch_1205_single out=ditch_1205_single_b4 type=area buffer=4
Could others try buffering this area? Maybe it fails for someone else?
GRASS> v.in.ascii out=ditch_1205 form=standard -n << EOF
C 1 1
# and then:
GRASS> v.buffer ditch_1205 out=ditch_1205_b1 type=area buffer=1
GRASS> v.buffer ditch_1205 out=ditch_1205_b4 type=area buffer=4
