Comment 3 for bug 890553

This bug hits me immediately after few minutes working with the reader + calibre.

How do you define / conclude the "corruptness" of the file in question?
I saw this error after deleting a book (from the reader UI) which was previously copied by calibre to the reader.
Could it be that the books.db has now one entry less than some internal calibre database, and so calibre expects to find non-existing data on the reader?

Andrey
