Bug#969546: freecad: Freecad crashes when placing beam in Arch workbench

Dear Maintainer,
I could reproduce this crash and first lines of the backtrace
with full debug symbols shows like in [1],
while trying to dereference a null pointer.
This might be a use after free because when trying to reverse execute
to the point where the memory holding the null pointer is last written,
we end in [2], which seems destroying the container pyObj=0x7f987942c7c0.
Full backtraces and starting from a minimal VM in attached file.
Kind regards,
Bernhard
