[Pkg-electronics-devel] Bug#1101443: kicad: colors lost on 3D models when exporting STEP

[Bernhard]

Package: kicad
Version: 9.0.0+dfsg-1~bpo12+1
Severity: normal
X-Debbugs-Cc: schlimmchen at posteo.net

Dear Maintainer,

there seems to be a regression when exporting a board from pcbnew to the
STEP format. When opening/importing the generated STEP file in FreeCAD,
no 3D model of a component has coloring.

For tests, I exported a STEP file of the demo project "pic_programmer".
The STEP files with colors are ~500kB larger than those without.

The problem only concerns Debian bookworm when installing KiCAD 9.0.0
from bookworm-backports. To be sure I reproduced this in a VirtualBox
running Debian bookworm as well.

The problem does NOT occur on
 * Debian bookworm with KiCAD 8.0.8
 * Debian trixie with KiCAD 9.0.0
 * Debian bookworm when using the flatpak package of KiCAD 9.0.0
 * Windows with KiCAD 9.0.0 and 9.0.1-rc2

Given that the flatpak package works as expected on the same host that
KiCAD 9.0.0 form bookworm-backports fails, I assume a run-time or
build-time dependency is missing?

Thank you for looking at this,
Bernhard
