Cool - fyi, I applied that patch locally and it does appear to solve
the problem.

Thanks. Destroying a NULL struct gtk_text_input from
registry_handle_global_remove() looks like
https://gitlab.gnome.org/GNOME/gtk/issues/129#note_91002
which looks like it would be addressed by
https://gitlab.gnome.org/GNOME/gtk/merge_requests/89 which is awaiting
upstream review.

This seems very unlikely to be a gnome-terminal bug if you also get it
for corebird. I'm guessing GDK or GTK+, which are in the same binary
package so it doesn't really matter which one has the bug.

Please could you retry this backtrace with libgtk-3-0-dbgsym installed?

I can't say for sure from the backtrace without debug symbols, but this
looks a lot like  (but we
thought we fixed that in 3.22.29-2) or
 (which has a patch waiting
for review upstream).
