printing hatches to PostScript produces spurious lines

[Arno Peters]

I will attach a sample DXF file and the corresponding PostScript output

How to reproduce:
1. open qcad.dxf in QCad
2. print the drawing to file
3. look at the generated PostScript file, between the hatch elements are spurious lines that are not in the DXF drawing.

These artefacts are also visible when using the vec2web tool from Ribbonsoft. This means the bug is probably located in either the dxflib or the qcadlib.

I am using QCad version 2.0.5.0-1-1

Further investigation seems to indicate the problem is located in the Qt libraries. The generated PostScript says:

%!PS-Adobe-1.0
%%BoundingBox: 0 0 594 842
%%Creator: Qt 3.3.6
%%CreationDate: ma dec 4 10:14:57 2006
%%Orientation: Landscape
%%Pages: 1

Maybe this problem is resolved with a newer version of the Qt libraries?

Is this symptom still reproducible in 8.10 alpha?

I have tested the DXF with Ubuntu Intrepid. The problem is still present.
