Description Silviu Marin-Caea 2016-03-01 11:35:15 UTC 
After applying latest updates (2016-03-01), KDE does not start properly anymore, it's just a black screen after login.

I even tried reinstalling the whole machine and applying updates, then creating a new user.

It's reproducible.

Here's what happens after login:

Hi

I can confirm the problem with the latest upgrade. Login to plasma does not work. A login with gnome works, but kde applications do not start anymore.

E.g.:  

# konsole
QCoreApplication::arguments: Please instantiate the QApplication object first
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
ostahl@lx16:~> konsole: relocation error: /usr/lib64/libKF5KDELibs4Support.so.5: symbol _ZN15QGuiApplication35setFallbackSessionManagementEnabledEb, version Qt_5 not defined in file libQt5Gui.so.5 with link time reference

Got same issue. After clean installed on 2 PCs and applied updates got the same black screen after log in and KDE loading screen. I can see only the mouse cursor on a black screen.

This should be fixed already, just update your system again.

And rather see Bug#968877, this one has been marked as duplicate.
