[Charlie Kempson <998585@xxxxxxxxxxxxxxxxxx>]

On my backend server, running 0.25 fixes or 0.26 fixes, this happens
consistently.  I can neither open the frontend or the setup programme,
which is a little inconvenient.  The server is a quad-core  headless,
but i did try pluggin in a monitor and the same thing happened, so I
don't think this is related to the headless nature of the machine.  Is
there a known workaround for this yet?
