[Shotwell] Database empty

[Malcolm Locke]

So, I just upgraded my Ubuntu laptop to 11.10, and the upgrade includes
Shotwell 0.11.2.  My previous version of Shotwell would have been 0.7.2,
from Ubuntu 10.10.

My library is now shown as empty, and my database appears completely empty.

  sqlite> select count(*) from PhotoTable;
  0

To it's credit, Shotwell appears to have made a perfect backup of the
completely empty database:

  $ md5sum .shotwell/data/photo.db*
  d5cea437bc167b9e1a7a00590d100e13  .shotwell/data/photo.db
  d5cea437bc167b9e1a7a00590d100e13  .shotwell/data/photo.db.bak

Thankfully, it looks like all my pictures are still there.

Do I have any chance of ever getting back the many hours I've spent
tagging my photos?
