> > Crashing happens in
[http://trac.osgeo.org/grass/browser/grass/trunk/lib/vector/Vlib/level_two.c#L356
level_two.c] in wxdigit.py in _addFeature. Without the line, the area
closes without problem, so maybe _breakLineAtIntersection is where
something goes wrong.

> The problem is in
[https://trac.osgeo.org/grass/browser/grass/trunk/gui/wxpython/vdigit/wxdigit.py#L1772
wxdigit.py] in _addFeature: the line is broken, afterwards the digitizer
tries to get the areas for this line. But this line no longer exists
because it has been broken into new lines -> crash.

> You would need to get areas on each side before breaking the line, but
the vector lib might only be able to build areas after the new line was
broken. I would suggest to break the line only after trying to attach
centroids.
Fixed in r63077.
