Comment 4 for bug 1497963

Partially solved it. This SO20 footprint in the Gen7Board layout causes an attempt to draw a circle with zero linewidth, which leads to a division by zero, which leads to invalid PostScript. These 5 pages aren't missing, but the printer driver outputs only up to the PostScript invalidation. The PS exporter exposes the same problem.

The fault happens in ps_draw_arc() in src/hid/ps/ps.c. Not yet found why drawing such an odd circle is attempted, there must be another bug. Possibly a bug when flipping the footprint from front to back.
