ValueError: Invalid IV size (15) for CFB8. - Upgrade from 3.0.8 to 3.0.14

[Anthony]

I upgraded from 3.0.8 to 3.0.14. When I look at a diff of my git-managed code, I get the following error:

There was an error displaying this diff.

  Invalid IV size (15) for CFB8.

Any idea what's causing this?

Hi Anthony,

Did you also dump/re-import your database? Or rebuild your site directory and generate a brand new $sitedir/conf/settings_local.py file? This can happen in either case.
