problem extracting features of straight lines

[ozymaxx]

The following error happens while extracting features of straight lines:

/usr/local/lib/python2.7/dist-packages/sketchfe/Sketch.py:44: RuntimeWarning: divide by zero encountered in divide
coords = coords * ( 1 / sdev )
/usr/local/lib/python2.7/dist-packages/sketchfe/Sketch.py:44: RuntimeWarning: invalid value encountered in multiply
