Did you actually do a conversion to kepub? Or are you using the KoboTouchExtended driver to transform the epubs to kepubs? These work in very different ways. If it was an actual conversion, then I would not expect an error. A suggestion of how to fix these sort of problems is to do an epub-to-epub conversion. That will fix most errors in an epub. And an epub-to-kepub conversion is basically an epub-to-epub conversion plus adding the spans. Doing this would have definitely fixed this error.
Yes, they have changed something and missed catching an error. I have reported the problem pointing at this thread. Hopefully it will be fixed in the next update.
But, as a note, sideloaded kepubs aren't really a supported format. The only reference to them is as a suggestion for book creators to test their books before submitting them to Kobo. Kobo could come back and say "unsupported, fix the book first". I don't expect them to, but, it is a valid response from them.

Good info there. I was using KoboTouchExtended to convert my epubs and mobi files to kepub when transferring to the Forma. I'll do your recommended epub-to-epub conversion while I wait for my replacement Forma to arrive. Hopefully it won't have the lightbar issue either.
