The Kaffeine version you're using is too old. We just released upstream a version 2.0.1, with is based on KDE5, and changed both the DVB and video play backends. Could you please test the upstream version and see if it works? The README file contains instructions about how to compile it. You can find it at our git repository: https://quickgit.kde.org/?p=kaffeine.git With the new version, I did some tests here by playing a video stream while manually killing pulseaudio on another window on Fedora 23. I didn't see any Kaffeine crashes. Obvously, audio stopped working, due to the lack of pulseaudio, but this is expected. As this BZ is on an old version that we're not maintaining upstream anymore, I'm closing the bug. If you find similar issues with version 2.0.1, please re-open.
