Ouch.

Other than shipping a yet-to-be-written perl script that uses
libberkeleydb-perl and tries to open the torrus databases, I am not
aware of any. We could invoke that script from postinst and run
db_recover if the script fails.

Unfortunately, I do currently not have the time to write this
ten-liner as I don't know enough about berkeley db. I am therefore
tagging this bug "help" and would appreciate if somebody could write
such a script.

I have added this to README.Debian.
