Have you used LaTeX with matplotlib in the past? What happens if you remove the line:

rc("text", usetex=True)

I had the same error on Mac OS 10.9.5. The culprit was Apple, in particular its stock python and matplolib.
When I install the unadulterated version of python and matplotlib, the example ran without error.

$ brew install python
$ /usr/local/bin/pip install matplotlib
$ /usr/local/bin/pip install daft
$ /usr/local/bin/python example.py

My Script was working before, suddenly I got the same error. I spent almost an hour to find it and it did not help me at all. I closed the shell and run it again, then it worked. I don't know why there was a problem and when I close and reopen my spyder not book, it worked.

That's bad. Should we close this bug for now?

Works.
To make sure there's no ambiguity I wrote:
rc("text", usetex=Fal=se)

It came back - the error. Just flagging this for other people trying to use cornerpy with latex.
and setting usetex=False helps.
