 Hi Mark!

 Another possibility is :
  1. You upgraded from 0.3.1-6 to 0.5-1.
  2. dbconfig-common make a backup of the database
  3. An error occurred on database upgrade because of already existing 
 indexes
  4. You abort the upgrade
  5. You try again to upgrade (to 0.5-1 or some newer version)
  6. dbconfig-common overwrites the backup of the database with the 
 half-upgraded database

 Does this scenario seems plausible to you?

 Thanks.
