It comes from an error in the method gale_ryser_theorem. This theorem is
actually about filling a matrix with 0 and 1 when you know the number of 1
in each column and in each row, and this is totally equivalent to creating a
bipartite graph with a given

Going to take a look at it !
By the way, please try to precise what the bug is about in the subject...
For example "something wrong about graphs.DegreeSequenceBipartite".
(though it's very nice to report bugs in the first place !)
