Well, I can shed a little light on what might be doing this.
The offending code is resetting a line's points, like this:
parent_group_line.set(points=(x1,y1,x2,y2))
and notice that it is the parent group. The child's line doesn't cause the
segfault. (The parent is drawing a line from itself to half-way-to child, and
the child is drawinf another line from that half-way point to itself. So the
parent has one line, and the child has another.)
Any ideas?
