I tried to record the bug related to my typing but could not get Kazam work as root and as non-root, see following; I installed it by apt-get install kazam ffmpeg successfully but not properly because of the errors/warningsroot@masi:/home/masi# kazamTraceback (most recent call last):  File /usr/bin/kazam, line 127, in <module>    bus = dbus.SessionBus()  File /usr/lib/python3/dist-packages/dbus/_dbus.py, line 211, in __new__    mainloop=mainloop)  File /usr/lib/python3/dist-packages/dbus/_dbus.py, line 100, in __new__    bus = BusConnection.__new__(subclass, bus_type, mainloop=mainloop)  File /usr/lib/python3/dist-packages/dbus/bus.py, line 122, in __new__    bus = cls._new_for_bus(address_or_type, mainloop=mainloop)dbus.exceptions.DBusException: org.freedesktop.DBus.Error.NoReply: Did not receive a reply.

How to proceed?Hardware: Asus Zenbook UX303UAOS: Debian 8.5Linux kernel: 4.6 (backports' one)Graphics: modesetting and non-free package for skylake CPU supportCase in Kazam suppot: https://answers.launchpad.net/kazam/+question/378875 
Is this missing dependency-bug of Python3 in Kazam of Debian 8.5?
