System is rendered useless after Plasma 5.4.3 update KDEInit couldn't launch

[Sudhir Khanger]

Hi,

I updated my system to Plasma 5.4.3. After I reboot sddm theme was 
automatically changed. Half of the system tray applets aren't loaded. No 
system app can be launched anymore. It says KDEInit couldn't launch 'app'.
