tex rendering broken?

Martin_Wiebusch · October 31, 2014, 3:53pm

I am having trouble executing the example for typesetting labels with
latex from http://matplotlib.org/users/usetex.html. Copying the standard
example, tex_demo.py, to a file and executing it gives the following
output:

I just installed matplotlib 1.4.2 via pip, and executing the file
matplotlib-1.4.2/examples/pylab_examples/tex_demo.py from the source
tarball gives the same error:

I just downgraded to matplotlib 1.1.1 and now everything works. Looks
like a regression to me.
