I have tried that too (alas). I will wait and see if 1.2 is happier with it. Curiously the book is from Tor UK and makes much of the fact that there is no DRM (which is good, of course). Except that Amazon UK delivered it to me with DRM, which I routinely stripped. I attempted to convert the original file and Calibre complained about that, but the stripped/converted ePub is the one Marvin doesn't like.
