Hi Michael,

it looks nice, but it does not seem to work for me. When I draw the
profile and click on the "create profile" button, I get:

  File "/usr/src/gis/grass/addons/gui/gui_modules/profile.py", line 320,
in CreateProfile
    self.pline = plot.PolyLine(self.datalist, colour='blue', width=2,
line 224, in __init__
    PolyPoints.__init__(self, points, attr)
line 124, in __init__
    self._points = _Numeric.array(points).astype(_Numeric.Float64)
ValueError: matrices are not aligned for copy

Thanks for this effort
