    Description

      Certain dbus calls onĀ /ApplicationInterface from with an application cause sysui to crash due to abort in libdbus.

      Assume following called in a programmatic manner from with an application of runtime 'qml' (probably the same for 'native'), it would lead to a sysui crash

       dbus-send --peer="unix:path=/tmp/dbus-qtam/dbus-qtam-<HASHID>" --type=method_call --print-reply "/ApplicationInterface" "org.freedesktop.DBus.Properties.GetAll" string:"io.qt.ApplicationManager.ApplicationInterface"

      here the backtrace:
