I have a file that makes QCAD crash. I’ve been editing this design across different versions of QCAD over time and this is the first time I have a problem with it.

Steps to reproduce:
Open the attached file and try to add some entities or dimensions to it (you may need to create large ones since it seems to depend on the zoom factor; for example a very large ellipse). After a freeze of a few seconds QCAD will quit.

The attached file is a simplified version from which I deleted a number of entities; on the original I can’t do anything – QCAD crashes as soon as I try to create any object.

Cause: 3D lines with x1==x2, y1==y2 but z1!=z2

This task depends upon
