I have recently found a number of my books ending prematurely when reading on my Kindle or Cybook. On investigating I have found that PRC files added to Calibre have been converted to MOBI. (Prior to about March PRC files were stored as PRC.) At this stage the books are complete. Only when sent to the device, Cybook or Kindle, are the files apparently corrupted.

Debug output for adding and sending 2 PRC and 1 MOBI files:

Have I done something really stupid or is there a problem?
