--- Comment #12 from Regina Henschel <rb.henschel at t-online.de> ---
You get the same problem with current applications: Draw a polygon in Writer
and export as docx. Because of the fix for tdf#75254 this does not generate a
custom shape but only a VML shape. Open the file in Word and add a point to the
polygon. Save it in Word. Word converts it to a v:polyline element without
adding a custom shape. This does not happen in PowerPoint. I have not tested
Excel.

Word writes the values in the attribute "points" with units, e.g.
31.2pt,297.7pt. But the import does not consider units.

The error is in
https://opengrok.libreoffice.org/xref/core/oox/source/vml/vmlshapecontext.cxx?r=e12d4c7e#572

Because the token contains the unit, toInt32() returns 0.

If such edited shape is copies from Word to PowerPoint, then it is converted to
a custom shape. I don't know whether older PowerPoint versions create
v:polyline. It might be necessary do distinguish applications anyway, because
of the Twips vs 1/100mm problem. The attribute coordsize, which Word produces,
is in Twips, but has no unit. So for Writer the token has to be converted to a
number value in Twips to match the coordsize attribute.
