gir1.2-keybinder-3.0 installs Keybinder-3.0.typelib into
/usr/lib/girepository-1.0/.

This is a legacy location, and is only searched because we apply a
Debian-specific patch to libgirepository. Instead, please install the
typelib file into /usr/lib/${DEB_HOST_MULTIARCH}/girepository-1.0.

The easiest way to do this (untested) should be to edit
debian/gir1.2-keybinder-3.0.install and replace:

usr/lib/*/girepository-1.0/* usr/lib/girepository-1.0

with:

usr/lib/*/girepository-1.0

When all of the 6 remaining packages that use the legacy location have
been fixed, we will be able to stop patching libgirepository.

Control: tags -1 + patch

Please consider
<https://salsa.debian.org/debian/keybinder-3.0/-/merge_requests/1>
(which also fixes several other long-standing packaging issues).

This is now one of only two packages that install into
/usr/lib/girepository-1.0/, so if both of those packages can be fixed
(or removed), we can stop patching gobject-introspection and glib2.0 to
check that location.
