Debconf errors cause clamav-freshclam installation failure

From the terminal log:

dpkg: error processing clamav-freshclam (--configure):
 subprocess installed post-installation script returned error exit status 128

I closed the app center before the install finished. The app seems to work as intended despite the error and the software center shows it as installed.

It looks to me like this is likely an error in the debconf package, not in clamav itself.

Status changed to 'Confirmed' because the bug affects multiple users.
