I'm getting an error with a mathtext string from the mathtext_examples:
import matplotlib.pyplot as plt
ax = plt.subplot(111)
s = r"$W^{3\beta}_{\delta_1 \rho_1 \sigma_2} = U^{3\beta}_{\delta_1
\rho_1} + \frac{1}{8 \pi 2} \int^{\alpha_2}_{\alpha_2} d
\alpha^\prime_2 \left[\frac{ U^{2\beta}_{\delta_1 \rho_1} -
\alpha^\prime_2U^{1\beta}_{\rho_1 \sigma_2} }{U^{0\beta}_{\rho_1
\sigma_2}}\right]$"
ax.text(1, 2, s)
plt.show()

Hmm... Can't reproduce this here. Maybe it's Python 2.4-specific (which I don't have).
As a workaround, does replacing line 216 with:
ParseFatalException.__init__(self, pe.pstr, pe.loc, pe.msg, pe.parserElement)
work?
