This is my current setup

   depends_on "glib"
   depends_on "gnutls"
-  depends_on "gtk+"
+  depends_on "gtk+3"
   depends_on "libetpan"
   depends_on "nettle"
+  depends_on "pygobject3"
+  depends_on "python@3.9"

And then failed with

Not sure why you label this as an upstream issue since the failing code is not even on upstream code base.
As already answered on upstream bug you need to fix your dependencies.
