Comment:

 Yes, bug, I have fixed it in QGIS changeset:12738 but it is not perfect.
 QGIS is using Vect_select_lines_by_polygon and it is selecting lines using
 bbox of the passed polygon. I have just set z coors to
 -PORT_DOUBLE_MAX/PORT_DOUBLE_MAX to cover 3D. It should be better
 specified in GRASS how Vect_select_lines_by_polygon treats 3D vectors, but
 until they touch the function, it works in QGIS.
