Very nasty, when I connect a SONY PRS-t1, PRST2 or PRST3 I get in 50% of the cases the error:

calibre, version 1.3.0
ERREUR : Erreur: Erreur pendant la communication avec l'appareil connecté

The SONY database is corrupted.  Delete the file /Volumes/READER/Sony_Reader/database/books.db on your reader and then disconnect  reconnect it. If you are using an SD card, you  should delete the file on the card as well. Note that  deleting this file will cause your reader to forget  any notes/highlights, etc. Underlying error:
Traceback (most recent call last):
  File "site-packages/calibre/devices/prst1/driver.py", line 293, in remove_orphaned_records
DatabaseError: database disk image is malformed

This makes calibre unusable for SONY PRS devices.
If I have a look on [URL="http://bazaar.launchpad.net/~kovid/calibre/trunk/view/head:/src/calibre/devices/prst1/driver.py"/devices/prst1/driver.py[/URL] I have the impression that the code should be able to continue to work even if remove_orphaned_records generates an exception.

When I let rebuild the books.db, the SONY PRS generates empty collections/collection database entries. I have added the two databases for an investigation.
