Qt warning when launching lxqt-config-notificationd

[isf63]

Current Behavior

When launching lxqt-config-notificationd a Qt warning is printed:
QCoreApplication::postEvent: Unexpected null receiver

This is my notifications.conf, for sake of completeness:

[General]
__userfile__=true
doNotDisturb=false
placement=bottom-right
screenWithMouse=false
server_decides=10
spacing=8
unattendedMaxNum=0
width=640

Possible Solution

Context

The Qt stderr message shows up upon launching from a terminal, and shows up in journalctl.
