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...

I have been using my iPhone to experiment with the "database disk image is malformed" error. I have some 8000 books to play with and my experience is that the error arises when the process of transfers from Calibre to Marvin glitches in some way and Calibre stops responding for a long time - it seems most easily triggered by marking a large number of books on Calibre for transfer to Marvin as one batch, particularly if the books are large. I think the batch size that triggers the problem may be related to the amount of RAM available to Calibre.
