| Plasma 5 is not starting here either. I did get an error message after several tries:
 kwin_x11 PID: 2719 Signal: Segmentation fault (11)
 Writing from another computer, before upgrade

 Hello list!
        
 I'm on Debian Stretch and today, after an update, Plasma 5
        doesn't
 start anymore.

 First of all, sddm doesn't show at each reboot and when
 it doesn't I have to restart it (# service sddm restart), it is
        the
 first time I see it behaving like this. When I successfully log
        in I
 see the splash screen of Plasma 5 but the progress bar gets
        stuck near
 the end and then nothing happens.
 
 I thought it could be a problem with some configuration files so
        I
 created a new user in order to have a clean home dir and I tried
        to
 login with it, but unfortunately the problem reappeared. Also I
        tested
 the login using lightdm instead of sddm, but nothing changed.
 
 These tests lead me to think that this issue is related to the
        packages
 updated today. Do you have any suggestions to further
        investigate this
 problem? Is there someone else who experienced the same issue?
 
 Please add me in CC if you reply, thank you.
 
 Best regards
 Francesco
 
 I downloaded libkdecorations2-5_5.3.2-1_amd64.deb and
      libkdecorations2private5_5.3.2-1_amd64.deb from
      https://mirrors.ocf.berkeley.edu/debian/pool/main/k/kdecoration/
      to my /home/jimmy and installed them one at a time using 'dpkg i
      libkdecorations2-5_5.3.2-1_amd64.deb' and 'dpkg i
      libkdecorations2private5_5.3.2-1_amd64.deb' and was able to
      downgrade with no problems, all other packages have been upgraded,
      rebooting and login with no problem. I hope this helps anyone who
      got hit by the bug.
