I replaced my simple ListStore subclass with an implementation of the TreeModelIF (based on the code in the GtkD demos DemoCustomList example) and updated on github/debfind. And I get exactly the same crash.

If you've any other suggestions I'll have one last try, but otherwise I think I've reached the end of the road with GtkD!

I've tried debugging the issue a bit more, but so far i only succeeded
in changing the error message to:

"This program exited with exit code -11"

which isn't very helpful.

I also found this: https://gitlab.gnome.org/GNOME/gtk/-/issues/1143 only
that is a textview in a scrolledwindow.
