Problem with kobo driver (fw 5.x) and cover image
While I was trying to adapt the kobo driver to the new tolino fw 5.11.230427 (no significant db changes, just updating version numbers) I noticed that calibre does not upload the cover image anymore. I think™ that it worked with 5.10.x. And there have not been any relevant db changes.

So I wonder what happened. Have there been any code changes recently that might have broken something?

Here is some debug output (notice the "No rows exist in the database" entry):

Code:

Any ideas how I can debug this further?
