[Qtwebengine] BUG: arguments to dbus_connection_dispatch() were incorrect

[Kevin Truong]

Forgot to mention in case it changes anything: the new machine doesn't have
any display on it. I am using Xdummy to run Qt WebEngine (an X server with
a dummy video driver), and this set up works perfectly fine on the other
machines with no errors or warning printed.
