Hi, digging to this old question, I eventualy installed the git version and, unfortunately, I still have the problem of edge id...

>>> from graph_tool.all import *
>>> g=load_graph('test.xml')
>>>
>>> _vertexIds = g.vertex_properties["_graphml_vertex_id"]
>>> _edgeIds = g.edge_properties["_graphml_edge_id"]

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/site-packages/graph_tool/__init__.py", line 1049, in __getitem__
    val = self.get_func(self.g, key)
  File "/usr/lib/python2.7/site-packages/graph_tool/__init__.py", line 1542, in <lambda>

    lambda g, k: g.__properties[("e", k)],
KeyError: ('e', '_graphml_edge_id')

Yes.
