Hi, I installed the new package and while it seemed to work fine at first, I ran into the following problem when drawing a graph: Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/graph_tool/draw/gtk_draw.py", line 315, in layout_callback pos_temp = ungroup_vector_property(self.pos, [0, 1]) File "/usr/lib/python2.7/dist-packages/graph_tool/__init__.py", line 759, in ungroup_vector_property _check_prop_vector(vprop, name="vprop", scalar=False) File "/usr/lib/python2.7/dist-packages/graph_tool/__init__.py", line 633, in _check_prop_vector vals = ["vector<%s>" % v for v in scalars] TypeError: Couldn't find conversion for foreign struct 'cairo.Context' The reason is, that the Debian package does not depend on python-gi-cairo. Installing the package fixes above problem. cheers, josch
