I came across the same problem, and was unable to find a solution to the version I am currently using (2.76b).
I ended up going back a few versions (2.62) and it seems to work. There might be later versions where it works as well, but this was the only solution I could find that actually solved my problem.
Hope this helps!

I've no idea what could be causing that. I can't reproduce the error...
