Version: (using Devel) Installed from: Compiled sources If there's an invalid value for "Theme" in e.g. /etc/kde4/kdm/kdmrc, kdm fails to start with an error "$THEMEPATH cannot get opened". The dialog only has a "OK" button, and when accepting the dialog, kdm quits. Instead, kdm should fallback to using no theme (like with an empty "Theme" setting). This currently affects Kubuntu Lucid users (see https://launchpad.net/bugs/517803).
