Bug 473249

Can you run this command in a terminal window:

QT_LOGGING_RULES='kscreenlocker_greet=true' kscreenlocker_greet --testing --theme /usr/share/plasma/look-and-feel/org.kde.breeze.desktop/

And paste the text it outputs into a comment here?

Command:
QT_LOGGING_RULES='kscreenlocker_greet=true' kscreenlocker_greet --testing --theme /usr/share/plasma/look-and-feel/org.kde.breeze.desktop/

 Output:
 QT_LOGGING_RULES='kscreenlocker_greet=true' kscreenlocker_greet --testing --theme /usr/share/plasma/look-and-feel/org.kde.breeze.desktop/
bash: kscreenlocker_greet: command not found

After specifing the paths:

Qt depends on a UTF-8 locale, and has switched to "C.UTF-8" instead.
If this causes problems, reconfigure your locale. See the locale(1) manual
for more information.
