Comment 1 David Edmundson 2018-12-05 23:26:47 UTC 
Can you reproduce the issue?

debug symbols for #7  0x00007f633de68398 in  () at /usr/lib64/qt5/plugins/plasma/dataengine/plasma_engine_mpris2.so

and #6  0x00007f636a407974 in Plasma::DataContainer::getDataEngine() () at /lib64/libKF5Plasma.so.5

will help

Sorry, I don't remember the exact conditions. I can watch videos now.
Comment 3 ali.sherif10 2018-12-06 06:02:05 UTC 
I think I found the reproduction conditions!
Click close to end at the progress bar then try close the player many times. I won't close at first. Finally, you'll get a crash that you can't report, because of useless backtrace.
It seems Firefox is independant of the problem.
Comment 4 Marco Martin 2018-12-14 16:38:33 UTC 
can this be replicated with more debug symbols installed?
