latex and saving in svg


It seems that saving in SVG is not possible if I use default latex
fonts in my plot. Do you have any suggestions? This is the error that
I get:

UserWarning: Could not match Computer Modern Roman, normal, normal.

  warnings.warn('Could not match %s, %s, %s. Returning %s' % (name,
