I was removing the KDE Plasma Desktop package from the Software Center, which removed the KDE Standard Desktop package as well. However, once the package finished uninstalling, I clicked on the KDE Standard Desktop package, which still had the 'Remove' button, as if it were still installed. I clicked on the button, which showed a popup saying the package was not installed, and didn't need to be removed. Then the software center crashed.
