KDE is unusable. 5.7 went from testing and bug still persists.

I am experiencing the same bugs.

Comment 8 Ivan Čukić 2016-09-23 16:50:25 UTC 
If that many applications segfault, there is most likely a problem with your setup, but I have seen this issue elsewhere as well, so I'll try to reproduce to see what the problem is.
Comment 9 Ivan Čukić 2017-01-15 09:15:08 UTC 
Qt 5.8 should have the fix for that crash.

But, you still have a problem with your setup - kactivitymanagerd only crashes when something requests it to exit - if it does it often, it means that most likely xcb connection to the X server is getting disconnected all the time.

And that tends to be from driver issues or distribution issues.
