I have not been able to repro the "database disk image is malformed" error. I have tried both ios 7 and 8; but I only have 300 books in my Calibre library and the error seems to be related to the number of books (more than I have).
I have created a new Calibre library, and I am going to load 1000s of copies of the same epub into it. I think this may take some time...
