Source: python-aiortc
Version: 1.3.2-1
Severity: serious
User: debian...@lists.debian.org
Usertags: regression

Dear maintainer(s),
With a recent upload of python-aiortc the autopkgtest of python-aiortc fails in testing on armhf when that autopkgtest is run with the binary packages of python-aiortc from unstable. It passes when run with only packages from testing. In tabular form:
                       pass            fail
python-aiortc          from testing    1.3.2-1
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 to testing [1]. Can you please investigate the situation and fix it?
