I think when this plugins try to read or write the reading status of ebbok, something is wrong.
If you are still seeing the above error, then it is has nothing to do with Kobo Utilities plugin. That error is happening while the driver is trying to get the list of books from the device. And it is probably happening when the database on the device is first accessed. If the Kobo Utilities plugin is causing a problem, it happened when you last connected the device. And it doesn't write to the database except when you manually start one of the functions that do updates.

The reasons for the database being corrupted are unknown. It can happen if the device is not ejected properly. I think it would also happen if two applications tried to access the database at the same time. So running calibre and the Kobo desktop application at the same time is not recommended. Otherwise, it is something happening when using the device. Something might be crashing and corrupting the database. But, I don't know what. In the Kobo forum I recently made some suggestions for trying to find when it happens, but, there have been no results from that yet.

And for the record, it would be a rare day where I didn't plug one or more of my Kobo ereaders in. And I fetch the reading status from them when I do. I rarely see a corrupt database. And mostly I know because I messed up and accidentally unplugged the device. I would love to be able to say what it is that is causing this, but, I just don't know.
