Comment(by strk):

 I've tweaked the GEOS part to return LINESTRING EMPTY rather than NULL
 when there's a collapse. This should give you something somewhat more
 acceptable than a segfaut.

 In any case the patch should be rewritten to encode side in the width
 parameter (positive for left, negative for right) and to use the
 GEOSOffsetCurve API.
