[Python-modules-team] Bug#862054: python3-igraph: error when plotting graph inline in jupyter notebook

[Jorge Moraleda]

Package: python3-igraph
Version: 0.7.1.post6-3
Severity: normal

Dear Maintainer,

Attempting to plot within jupyter notebook yields the error:
AttributeError: 'bytes' object has no attribute 'encode'

This code reproduces this bug when typed inside a jupyter notebook:
import igraph
G = igraph.Graph.Erdos_Renyi(100, 0.1);
igraph.plot(G)

This bug agains the python igraph package is discussed in greater detail at https://github.com/igraph/python-igraph/issues/88 and was fixed in the 0.7 release branch of python-igraph that debian includes on August 5, 2016 (https://github.com/igraph/python-igraph/commit/8864b46849b031a3013764d03e167222963c0f5d)

We should repackage the debian package python3-igraph with a later version python igraph that incorporates this fix as plotting is an important component of the igraph library. Thank you.
