well, i'd say just don't play p0rn audio ... whatever that may be =)

This backtrace however doesn't match the bug description. It says that you attempted to kill a process and accidentally killed kwin's kill helper dialog instead - what happens to (too) many users and will therefore at least no longer kill kwin in 4.9.

-> You should file  a new bug against dolphin.
Ideally and in case of a segfault alongside a matching backtrace, otherwise with a better description, like what do you play the file with, does it happen with every audio file, what phonon backend you do use and in case it only happes with specific files only (like such which are not the regular 44.1kHz / 16bit combo) link or attach one.
