Conversion to Mobi to ePub errors

I've been successfully using Calibre to convert my various eBooks over to ePub for Stanza with great success up until one book which errors out with the following message - any tips or should I file a bug report? The mobi file opens fine with the Stanza desktop application and (mostly fine) with the Calibre eBook reader. Currently running 0.7.12 under 64-bit Ubuntu.

That error indicates a damaged file. Usually, damaged during DRM removal. Since the calibre viewer and the converter use the same code, I don't see how it is possible for the converter but not the viewer to work.

Definitely odd then...

Since I can read the file in several readers, including Calibre, but there's obviously an error blocking the conversion process.

Possibly an issue with extended character encoding in the book ? Would you like to see the file for testing?

Type Errors in un DRM'd conversions

I'm wondering why a novel I paid for in B&N and then transferred to Kindle has certain type-set errors (i.e. pol liti cle, de vil, Eng lish, etc) intermettently thoughout the document? There was discussion of errors from DRM removal. But it's not that.

This same annoying problem is not only noticed in the MOBI document on Kindle2 and Caliber; I also rechecked the original EPUB document, searched for an error word like "po liti cal" and there it was! So this is what B&N originally sent me?

Has anyone else had this problem with downloaded files they bought? Is it common or just B&N?

I don't believe that B&N formats the book, the publisher formats the book. I would write the publisher, B&N, and the author with the details and your dissatisfaction with the product.

If you wanted ePub, why did you purchase Mobipocket?
