On openSUSE 13.1 I have this for knotifications:

Could not find a package configuration file provided by "Phonon4Qt5"

Isn't this needed?

$ sudo zypper in libphonon4qt5 phonon4qt5-backend-gstreamer phonon4qt5-backend-vlc phonon4qt5-devel

Sorry for the late reply. I didn't check the wiki messages. Did you solve your problem?
