usetex failure in latex documents

When I use matplotlib's internal tex (rcParams['text.useTex']=False), the postscript files generated cause errors that look like this when you try to ps2pdf them:


ps2pdf h2co_pilot.ps

They will not open in MacOS's Preview.app either.

Solution: Make figures with rcParams['text.useTex'] = True
