#323 --graph=umlclasstree yields TypeError

[Anonymous]

I have a really simple project which uses the included configuration file. Making regular documentation with 'epydoc -v --config doc.conf' works very well. However when I add the '--graph=umlclasstree' flag to get a UML diagram, the program fails with a TypeError:

$ epydoc -v --graph=umlclasstree --config doc.conf --debug

I use version 3.0.1 and my system is ubuntu linux 9.04 (graphviz is installed).

Additional information:
It seems like the problem happens for a class which inherits Tkinter.Frame in the Tkinter package. Trying to make a class diagram for a file containing this:

import Tkinter
class foo(Tkinter.Frame):
pass

results in the same error. Perhaps there is some error in Tkinter, but still I think it should not effect epydoc.
