If the program parameter to the graph.write() method is a list then the script Errors out

What steps will reproduce the problem?
1. g = Dot(graph_name='G',graph_type='digraph',strict=True,overlap=False)
2. program=['fdp','-Nshape=oval']
3. g.write('g.pdf',prog=program,format='pdf')

What is the expected output? What do you see instead?

The output file should be created but instead the script errors out

What version of the product are you using? On what operating system?

Pydot 1.0.25 , Windows , Python 2.7

Please provide any additional information below.

    I have patched it up in my local pydot module.

    Please, provide the commit access to commit the changes.
