This kind of behavior has been seen before when symbol information is (for some reason) only partially available. IIRC, this occurred in Fedora, but I might be mistaken. d9a3b3b should fix it, however that hasn't been published to the PyPI.

Using the current git HEAD of this repository instead of the PyPI package should make the errors got away.
