Bug#948459: sympy breaks yt autopkgtest: FAIL: Create units with strings and check attributes.

[Paul Gevers]

Source: sympy, yt
Control: found -1 sympy/1.5-1

Dear maintainers,

With a recent upload of sympy the autopkgtest of yt 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    1.5-1
yt                     from testing    3.5.1-2
all others             from testing    from testing

I copied some of the output at the bottom of this report. @yt
maintainers, you want to look at the messages one sees after installing
python3-yt.

Currently this regression is blocking 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?
