I think I've found a bug in matplotlib. I use Sage, which is based on

Python and included matplotlib.

sage: import pylab

sage: pylab.text(0.2, 0.2, r"$\left(2a = b\right)$") # note \left(

and \right) work

<matplotlib.text.Text object at 0x10daaf950>

sage: pylab.text(0.2, 0.5, r"$(2 \, a = b)$") # note \, works

<matplotlib.text.Text object at 0x10dab9c90>

sage: pylab.savefig('a.png')

sage: pylab.text(0.2, 0.7, r"$\left(2 \, a = b\right)$") # but

together they don't

<matplotlib.text.Text object at 0x10dad9b10>

sage: pylab.savefig('b.png')

ERROR: An unexpected error occurred while tokenizing input

...

AttributeError: 'Kern' object has no attribute 'height'

Is this repeatable for anyone else? Would the full traceback be helpful?
