gtksourceview2 has not had an upstream release since 2010.

The Debian GNOME Team would like to remove it from Debian. Please port
your package to gtk3 and gtksourceview4.

Because of the late filing of this RC bug in the Buster release cycle,
please contact us if you object to its removal from Buster.

Thanks,
Jeremy Bicha
