One other thing you might want to check is that at least one of the
slr-pentax.xml files somewhere in one of the database paths has all the
mappings (<compat> tags) between the many Pentax K-something mounts, as found
at the top of the current git version:
https://github.com/lensfun/lensfun/blob/master/data/db/slr-pentax.xml
The copy of this file shipped with 0.2.8 is very old, and incomplete in this
regard. If you've updated with the lensfun-update-data script, it should have
taken care of that, but it could be one reason that valid profiles don't show
up even for manual selection with a given camera.

The attached database file works for autoselection on my darktable built
against lensfun 0.3.2, both with the provided samples and the others I found.
Good luck!
