Summary0001370: Cannot Render Multiple Graphs in Threads

I am trying to render multiple graphviz graphs with the included
gtk plugin in threads.
The first graph will always show up. However, when I try to launch
the second graph, it will not open until the first graph is called.
I have attached a very small sample python script that demonstrates the problem.
Here I was just using one of the sample dot files included with graphviz,
and that does not work either. Even an empty dot file as the same problem.

Also, when I called gv.render, with or without a thread, I have to press
the close button twice. After the first time, the window appears again
and then clicking the close button a second time closes it.
import gv, thread
graph ="graphviz-2.20.2/graphs/directed/")
gv.layout(graph, "dot")
thread.start_new(gv.render, (graph, "gtk")) #this graph works fine (although for some reason you have to press the close button twice)
thread.start_new(gv.render, (graph, "gtk")) #this graph will not show up until the first one closes
Steps To Reproduce

Any dot file, even an empty one should suffice.
