[graph-tool] Problem with graph tool visualization

I tried to plot a graph or run the animation example. But, I always get this error cairo_surface_set_device_scale. Importing graph_tool,gi and pygtk is not a problem in python. Has anyone had this problem before? I am using ubuntu 14.04 and python 2.7* (anaconda distribution). -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/...
