Error when trying to plot simply sin(x) in gnuplot:

plot sin(x)
./src/gtk/dcclient.cpp(2041): assert "m_window" failed in DoGetSize(): GetSize() doesn't work without window [in thread 816606000]
[xcb] Unknown request in queue while dequeuing
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
Assertion failed: (! xcb_xlib_unknown_req_in_deq), function dequeue_pending_request, file xcb_io.c, line 179.
Abort


Plotting data also abort immediately with

./src/gtk/dcclient.cpp(2041): assert "m_window" failed in DoGetSize(): GetSize() doesn't work without window [in thread 817f08000]
