[igraph] Question regarding graphml format reading

[Robin Müller-Bady]

Dear list,

I have a graphml file which contains the "full" dataset of the european 
interconnect network:
http://www.topology-zoo.org/eu_nren.html

You can find the problematic file here:
https://mueller-bady.com/owncloud/index.php/s/eR9YfNDy8tujno2

Unfortunately, reading the graphml file with igraph results in the 
following problem:
$> In [1]: g = Graph.Read_GraphML("interconnect.graphml")
$> python: igraph_strvector.c:467: igraph_strvector_size: Assertion 
`sv->data != 0' failed.
$> Aborted
I work under debian linux using igraph 0.7.0

Any ideas?

Thank you very much in advance!

Best regards,
Robin
