I'll add some code when I get a chance to silently handle this case, but it's a problem with the creator of the book.
Ebooks are in The Netherlands , sorry for the words, "a pain in the ass".
They try to create them with fonts that are not copyrighted but designed by their own.
Most of the time this are fonts that are not dark but more grey,they don't look sharp,they have all kinds of errors,2 times a front with picture in it and much much more problems.
99% of all the books selled by multiple vendors (like Bol.com or Kobo) are downloaded from one source "the central bookhouse" so the stores only works as a selling channel (frontend), you pay,get a link and the link downloads it from the central bookhouse" but they all use somekind of their own social DRM.
Some of them just add an "invisible" watermark, but others also change the internal html files to this watermark number.
Nothing wrong there, but it happens a lot that the social DRM doesn't work right so you get 2 kinds of errors:
1. Name is changed in the spine but the HTML files are not renamed.
2. Names are changed in the HTML but not in the spine.
They think, as long as the index is correct, the books are transferred correct, which they are with the Kobo desktop program.
They are also send wireless and there is no check or something so they are ok on the reader.
But at the moment you use Calibre and your plugin,the error stops the transfer. (just because the plugin works correct and does the check THEY should have done)
When you contact the vendor and try to point them at the problem,they just answer "we don't support Calibre" (or whatever other program you use).
Most of the time when an error occurs I first load it into Sigil and try to fix it there...
The truth for most bookstores here is that they don't like the epub's because they are so much pirated spread, they don't give any support and most of the time they release a paper book first and the ebook a couple of days or weeks later,so a lot buy the paper book instead..

Thank you for adding the "silent" mode.. giving the support the vendors must give actually.
