Since the problem happened after an update from your distribution, please address this to our distribution, we didn't change anything on our side. This is likely to be a mix up with Qt4 and Qt5 libraries. FWIW: you will need to install debugging symbols for the backtrace to be useful, and the problem is clearly with the vlc backend, not with Amarok
I also have the same issue. It started after the most recent distribtion updates. Also affects Digikam as well as Amarok.
