It looks like Phonon is configured with VLC backend, but VLC is based on Qt 4, and loading it into the ELF namespace of a Qt 5 based application will not work.
I am not sure whose "fault" it is (Phonon or VLC), but this certainly does not look like a Konsole issue. Reassigning to Phonon maintainers for inspection.

Interesting.
It looks like Phonon is configured with VLC backend, but VLC is based on Qt 4, and loading it into the ELF namespace of a Qt 5 based application will not work.
