Testing anomalies - help needed

Harald told me to uninstall phonon-backend-vlc, and install
phonon-backend-null, which I did. However, when Amarok starts up,
after a restart of KDE:

bool Phonon::FactoryPrivate::createBackend() Phonon backend "VLC"
version "0.5.92" loaded

Whole paste: http://paste.kde.org/532784/

Diagnostics tab continues to report 0.4.55, as does the config dialog.
Also, now pgst doesn't show in the config dialog, although it is

And Diagnostics continues to report that pulseaudio is not installed,
although it is installed from packages.

Any help?
