GLib-CRITICAL

[simonjcarr]

When I run the code below, the map opens correctly in FireFox but, there are no points on it and I get this error in the python console.

(process:22998): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed

        mymap = pygmaps.gmap(41.892, -87.629, 16)
        mymap.add_point(41.892, -87.629, "#FFFFFF","Bus:  4380")
        mymap.add_rad_point(41.892, -87.629, 20, "#FFFFFF")
        mymap.draw('./mymap.draw.html')
        url = './mymap.draw.html'
        webbrowser.open(url)

I am running on Linux Mint 17.2
