I have two open tickets related to symbolics, and sadly the new symbolics hasn't magically fixed either. :( http://trac.sagemath.org/sage_trac/ticket/4142 http://trac.sagemath.org/sage_trac/ticket/3863 I don't know enough about the pynac symbolics to try fixing this, but if anyone is looking for more test cases...
