Synaptic or Python error?

[JoeHill <joehill@teksavvy.com>]

Getting this error after any installing any packages with Synaptic: 

 E: python-elementtree: subprocess post-installation script returned
error exit status 2

I see this error occurs a lot when I search on it, but I can't tell if it's a
Python error or something with Synaptic.

I'm running a mixed Testing and Unstable system.

Any ideas?
