Same here. OS: Arch Linux: 4.6.2 x86_64 systemsettings5 crashes with that error/warning whenever I try to access "Sound and Video". I was trying to change phonon backend settings to see if Dolphin would stop crashing, haha.
Update: I've gotten this working now (Arch OS). I removed all phonon-qt*-vlc packages and installed phonon-qt*-gstreamer. I also installed vlc, which I thought was installed, but wasn't. Now neither dolphin nor systemsettings5 crashes on me. Phonon uses qt4 instead of qt5, not sure why then that the package phonon-qt5 even exists alongside phonon-qt4. But removing those phonon-qt[4/5]-vlc packages and then installing phonon-qt[4/5]-gstreamer AND installing vlc was the answer for me. I'm not sure if only installing vlc may have solved this, but whatever.
Peter, can you confirm the issue was related to mismatching or missing phonon packages? I do not see these messages here.
I still get those messages and, on the Fedora 25 ("Rawhide") system I'm on right now, there is no "phonon-qt4" package available. (Both installed packages, phonon and phonon-qt5, are version 4.9.0-3.) Note that the messages are only visible them "phonon" is started from a command line.
Looks to have been fixed since then. I don't see these anymore.
