Comment 10 for bug 643910

This bug -- and others relating to calendar/task settings (such as day begin/ends setting and colour settings) -- are not present in the version of evolution at Jacob's ppa (https://launchpad.net/~jacob/+archive/evo230). Many people used Jacob's version in Lucid; being 2.30.3, it will also work in Maverick.

Download the packages to a temporary directory and do sudo dpkg -i *.deb to 'downgrade'. In Synaptic, lock all evolution packages to prevent updates overriding Jacob's ppa versions.
