Facebook Friends Graph fails when friends have a dash in their name

 I have friends that have a composed firstname (like : "Jean-Marie"). The dash causes an error in pydot when trying to draw the graph.

 I could solve it by modifying fbfriendsgraph.py in ConnectionsParser.run()
 I replaced :

edges.append((dictnames[j[u'uid1']], dictnames[j[u'uid2']]))

 by :

name1 = '"%s"' % dictnames[j[u'uid1']]
name2 = '"%s"' % dictnames[j[u'uid2']]
edges.append((name1, name2))

This has solve the problem and allowed me to see the resulting graph.

I don't know if this could cause other issues elsewhere, but at least it worked for me...
