I played around with native buffering (both versions) and they both
look similarly bad :(
Thus I made v.profile to hard depend on GEOS buffers (no native
option) till we manage to fix problems with native buffering.
Please test if trunk seems to be OK now (I added also a test case
based on your example).
r71769 will need a backport if there will be no objections.
