BTW: currently I am running one the test versions offered by gnucash via flatpak [1]. Version org.gnucash.GnuCash//maint-C4.0-98-g82da49efc-D4.0-5-g8eee199 works for me.
I would assume that the current stable version 4.1-1 from https://flathub.org/apps/details/org.gnucash.GnuCash should also work but I did not check that. Looking forward to switching back to Debian packages once it is fixed there. Thanks a lot for all the hard work. HTH, Markus [1] https://lists.gnucash.org/wiki/De/Flatpak#Beispiel-Einrichtung (German)
