   With python3.6 and wxpython installed via anaconda I get:

   E               subprocess.CalledProcessError: Command '['/Users/jklymak/anaconda3/envs/matplotlibdev/bin/python', '-c', 
   'import sys\nfrom matplotlib import pyplot as plt, rcParams\nrcParams.update({\n    "webagg.open_in_browser": False,\n

   returned non-zero exit status 1.
   

   which is slightly different.

   Can you copy-paste the script (e.g. directly from test_backends_interactive) and run it (setting MPLBACKEND to wx/wxagg)?

   Running

   import matplotlib
   matplotlib.use('wxagg')
   import sys
   from matplotlib import pyplot as plt, rcParams
   rcParams.update({
       "webagg.open_in_browser": False,
       "webagg.port_retries": 1,
   })
   
   fig = plt.figure()
   ax = fig.add_subplot(111)
   ax.plot([0, 1], [2, 3])
   
   print(rcParams["backend"])
   
   if rcParams["backend"].startswith("GTK3"):
       fig.canvas.mpl_connect("draw_event", lambda event: sys.exit(0))
   else:
       timer = fig.canvas.new_timer(1)
       timer.add_callback(fig.canvas.key_press_event, "q")
       # Trigger quitting upon draw.
       fig.canvas.mpl_connect("draw_event", lambda event: timer.start())
   
   plt.show()

   pops up and then closes a window and prints an error to the screen:

   Can you try with older wxpython releases then?

   Self-merging #11593 to unbreak the build, but someone should figure out whether this needs to be fixed (or not) before 3.0 goes out!

   Closing this as #11708 shows this is hanging rather than segfaulting now.
