Comment:

 yeah, this one has been around for ages. see also its very close relative
 bug #90, AIU it's the same bug in the cleaning code for areas. and there
 is Markus M's comments in #699 too.

 the ditches area given midway through RT bug # 2765 is better now though,
 but I'm not sure about the example at the end of the old report. (note
 that bug was for the first grass6 v.buffer module)
   http://intevation.de/rt/webrt?serial_num=2765



 thanks for pointing out the simple test case. I can reproduce it on 32bit
 linux with current grass 6.5svn.

 btw I've been sitting on an area I've got that makes the main cleaning
 steps place centroids wrong; I'll file that as another bug.
