Dear maintainers,

With a recent upload of lxml the autopkgtest of mypy fails in testing
when that autopkgtest is run with the binary packages of lxml from
unstable. It passes when run with only packages from testing. In tabular
form:
                       pass            fail
lxml                   from testing    4.4.1-1
mypy                   from testing    0.720-2
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of lxml to testing
[1]. Of course, lxml shouldn't just break your autopkgtest (or even
worse, your package), but it seems to me that the change in lxml was
intended and your package needs to update to the new situation. Please
reassign to lxml when I judged this wrong.
