#364 epydoc on object fails

[Lukas Pirl]

Documenting 'object' fails what probably leads to a build fail for every project that references object!? (I can hardly imagine this…)

$ epydoc --graph=all --debug object
Traceback (most recent call last): Progress: 00:00

The attached patch fixed it for me.

Probably fixed in [r1728]
