[Biopython] problems with Phylo.draw

[Vincent Davis]

I am working with some code that used to work (6 months ago) , I am not
sure what has changed other than upgrading to the current Biopython and
iPython versions.
I am using anaconda python 2.7
Development build of Biopython
Development built of iPython

You can download the file from Dropbox
here<https://dl.dropboxusercontent.com/u/1340248/homolog__1274p.clustalwF-gb.phylip_phyml_tree.txt>

t = 'old/phylo_tools/temp/homolog__1274p.clustalwF-gb.phylip_phyml_tree.txt'
tree = Phylo.read(t, 'newick')
Phylo.draw(tree, ext)
#Phylo.draw_ascii(tree)
