it would be fine if you could open a ticket in trac for this issue<br>
(<a href="http://trac.osgeo.org/grass/wiki#BugTracking" target="_blank">http://trac.osgeo.org/grass/wiki#BugTracking</a> ,<br>
<a href="http://trac.osgeo.org/grass/report" target="_blank">http://trac.osgeo.org/grass/report</a>) and, if possible, add a patch<br>
there (<a href="http://trac.osgeo.org/grass/wiki/HowToSVN#LocalDiffs" target="_blank">http://trac.osgeo.org/grass/wiki/HowToSVN#LocalDiffs</a>), so all your<br>
work isn't getting lost in the mailing list.<br>
<br>
best regards<br>
