Debconf problem: DbDriver "config": /var/cache/debconf/config.dat is locked by another process

[Graham Williams <Graham.Williams@cmis.CSIRO.AU>]

I've got myself stuck somehow with upgrading some packages (am current
with "unstable"). After a recent apt-get dist-upgrade I now have:

debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by
another process

and the various messages about 

  Package debconf is not configured yet.

Any ideas what I've done to get myself into such a pickle? And how to
get out of it.....

Regards,
Graham
