Evolution is not installed by default in 11.10, so I don't see how this can be blamed on bug #424643. But I also don't see how this can be blamed on Ubuntu Software Center. Even if I use apt-get, installing evolution also installs evolution-common, evolution-plugins, evolution-webcal, and libevolution, while removing it removes only evolution-plugins. That seems, straightforwardly, a bug in apt.
