I noticed that in this version, installed on openSUSE Leap 42.1 , the activity (play DVD with kaffeine, for example) when inserting a DVD is removed. According to https://bugzilla.opensuse.org/show_bug.cgi?id=960480 , this is an upstream problem Reproducible: Always
If I understood the openSUSE BZ, the problem seems to be related of Kaffeine using KDE 4. The newest version of Kaffeine (version 2.0.1) uses KF5 instead of KDE4. So, I guess this was fixed upstream already. So, I'm closing the bug as fixed.
