Todays update of libkf5screen7 breaks kscreen on KDE Neon. Display settings are not applied on login and "System Settings" "Displays" crashes with the following crash information: "Application: System Settings (systemsettings5), signal: Segmentation fault" Could't get more information from Crash Reporting Assistant. If I try to execute on terminal with command "kcmshell5 kcm_kscreen" I receive: kscreen: "The shared library was not found." QObject::connect: invalid null parameter Segmentation fault Old version of package was: libkf5screen7=4:5.12.5-0neon+16.04+xenial+build60 New version of package is: libkf5screen7=4:5.12.5-0neon+16.04+xenial+build61 Revert to old version with command "apt install libkf5screen7=4:5.12.5-0neon+16.04+xenial+build60" works. After revert everything works like before.
New available build 63 fixes the problems.
