I had the same problem, but my log started like this:

I've purged python-support, and solved the problem (i.e. it's installing now). It had only 6 packages depending on it.
>From your log "nodejs" might be the problem, maybe a leftover from some ppa. Proceed with caution when removing python packages.
Best,
Daniel
