Dear maintainers,

With a recent upload of sympy the autopkgtest of octave-symbolic fails
in testing when that autopkgtest is run with the binary packages of
sympy from unstable. It passes when run with only packages from testing.
In tabular form:
                       pass            fail
sympy                  from testing    1.3-1
octave-symbolic        from testing    2.7.0-1
all others             from testing    from testing

I copied some of the output at the bottom of this report, but it was too
difficult to quickly spot the real failing test.

Currently this regression is contributing to the delay of the migration
of sympy to testing [1]. Due to the nature of this issue, I filed this
bug report against both packages. Can you please investigate the
situation and reassign the bug to the right package? If needed, please
change the bug's severity.
