Fixed.
Thanks all. I'd chopped out the flatpak subsystem because of the overheads, so I tried downloading Ubuntu 18.10's gimp-python and installing it manually, fixing any dependencies it complained about, and amazingly it was really straightforward. Just two packages needed to be downloaded, which had no replacements to clash with, so although it's a bit of a hack, it seems safe enough. I'd already had to install a whole bunch of Python 2 packages for Inkscape, so the extra overhead wasn't significant for me. Heal-selection works. GMIC QT works.
