So I would like to back up my iBooks collection, but unfortunately iTunes is being a turd and ignoring the 10 or so non-iTunes books I actually care about in my collection when I try to back it up to iTunes. I used calibre to load these books on the device in the first place, so I'm not sure why it's having trouble now. I just want to back it up before upgrading to iOS 5!

The error I get is below:

Code:

calibre, version 0.8.21
ERROR: Error: Error communicating with device

'NoneType' object has no attribute 'location'

Traceback (most recent call last):
  File "site-packages/calibre/gui2/device.py", line 81, in run
  File "site-packages/calibre/gui2/device.py", line 446, in _save_books
  File "site-packages/calibre/devices/apple/driver.py", line 808, in get_file
AttributeError: 'NoneType' object has no attribute 'location'
