Digikam 4.6.0 is Qt4 based application ONLY.

The trace indicate a crash in Qt5 library. digiKam do NOT use Qt5.

So its a problem from your system. Report it as an UPSTREAM bug from your distro team.

Comment 2 caulier.gilles 2017-07-20 10:12:11 UTC 
It crash in Phonon. This KDE component is used to render video. Since 5.2.0, we
switch to QtAV/ffmpeg framework. So this problem will never appear again.
