Hello All,

What is probably happening here is that debian stable uses an older
version of the org.gnome.desktop.interface schema?
I see that the keys that the font rendering patch needs were added in
jan 2021:
https://github.com/GNOME/gsettings-desktop-schemas/commit/d6a804b3a73605f9f=
fe917c31b9eb1301f2c4b73

I'll have a look if it's possible to fix this by checking if these
newer font keys are present in the schema and not fetching their value
if they are missing (which is marked in the glib docs as a "programmer
error", which would explain the trap).

Kind Regards,

Pieter

I already fixed that bug, you don't have to concern yourself with it any
further.

Thanks.
