Package: libkscreenlocker5 Version: 5.22.5-1~np1 Followup-For: Bug #904074 X-Debbugs-Cc: martin+deb...@insulander.info
I found out I got this problem when using a world map as background in the lock screen, with package plasma-marble. Running the greeter manually gives a neet little error: ~$ /usr/lib/x86_64-linux-gnu/libexec/kscreenlocker_greet --testing QObject: Cannot create children for a parent that is in a different thread. (Parent is MarbleQuickPlugin(0x7fa7b00f4ed0), parent's thread is QThread(0x55e949fe5e20), current thread is QThread(0x55e949eab5b0) QWidget: Cannot create a QWidget without QApplication Avbruten (SIGABRT) (minnesutskrift skapad) So in my case it looks like the issue may be in plasma-marble.
