You can get a meaningful backtrace by enabling debug symbols, either by 
installing the dbgsym packages or by:

export DEBUGINFOD_URLS="https://debuginfod.debian.net"

With this I get:

I also reduced the code to:

import gi
gi.require_version('Gtk', '3.0')
from gi.repository import GObject, Gtk

class Terminal(Gtk.VBox):
     pass

GObject.type_register(Terminal)
Terminal()

And while this clearly does not involve terminator, I can only reproduce 
this on the console, whereas in an X session, with $DISPLAY set, it is 
not reproducible. Just as well terminator fails to build in sbuild but 
builds fine with dpkg-buildpackage in an X session. But even more this 
also fails in a bullseye chroot so this is all a red hearing.

The actual problem is that libgtk-3-0 version 3.24.30-1 drops the 
dependency on librest-0.7-0 which brought in gsettings-desktop-schemas 
which seems to be the missing build dependency as this works for unstable:

sbuild terminator --add-depends gsettings-desktop-schemas

Assigning back, accordingly, though I'm not sure if there should be an 
other bug for python3-gi or the gtk backtrace above.

Cheers Jochen
