Re: [igraph] error calling g.simplify()

[Tamás Nepusz]

For the record, the Python interface of igraph now imposes stricter checks on 
attribute names; only string or Unicode attribute names are now allowed, which 
means that your code would throw a TypeError when trying to construct the graph 
(because csv.DictReader introduces None as an attribute name when it encounters 
a column without a corresponding header name).  

The corresponding changes in the C and Python code are here:
