This suggestion did not resolve the problem.

But here is the solution. I have no idea why the first version is not
working.
I changed the threading technique:
  - from gobject.idle_add(run) to the fig.canvas.mpl_connect('draw_event',
start_anim)

I think it can be only that... Any ideas?

import matplotlib
matplotlib.use('GTKAgg')
from pylab import figure, show
import gobject, gtk
import time

fig = figure()
ax = fig.add_subplot(111)
ax.set_xlim(0, 30)

#fig.subplots_adjust(left=0.3, bottom=0.3) # check for flipy bugs
ax.grid() # to ensure proper background restore

ax.get_xaxis().set_animated(True)

fig.canvas.draw()


def run():
	if run.background is None:
		run.background = fig.canvas.copy_from_bbox(fig.bbox)
	
	fig.canvas.restore_region(run.background)
	i = run.cnt
	ax.set_xlim(0+i,30+i)
	fig.draw_artist(ax.get_xaxis())
		
	fig.canvas.blit()
	
	if run.cnt == 180:
		gtk.main_quit()
		raise SystemExit
		
	run.cnt += 1
	time.sleep(0.1)	
	return True
			


def start_anim(event):
    gobject.idle_add(run)
    fig.canvas.mpl_disconnect(start_anim.cid)

start_anim.cid = fig.canvas.mpl_connect('draw_event', start_anim)


run.background = None
run.cnt = 0

show()
