[OGDev] Upgrade broke my DB, I think

[Rev Simon Rumble]

Hi folks.

You may have noticed that the Tourist Engineer has been spammed to hell 
and back.  I just tried upgrading to the latest version using apt-get 
and, after accepting the new wiki.conf (there seems to be a bunch of new 
stuff) I got this:

Processing config file /etc/openguides/default/wiki.conf ...
Checking database schema...
DBD::SQLite::db prepare failed: file is encrypted or is not a 
database(26) at dbdimp.c line 269 at 
/usr/share/perl5/Wiki/Toolkit/Setup/SQLite.pm line 156.
DBD::SQLite::db prepare failed: file is encrypted or is not a 
database(26) at dbdimp.c line 269 at 
/usr/share/perl5/Wiki/Toolkit/Setup/SQLite.pm line 156.
dpkg: error processing openguides (--configure):
 subprocess post-installation script returned error exit status 2
 Errors were encountered while processing:
  openguides
  E: Sub-process /usr/bin/dpkg returned an error code (1)

Has the upgrade munched my database?  I've got a backup, so how should I 
go about recovery?
