Dear maintainer,

the autopkgtests of python-libtmux are flaky:

See
https://ci.debian.net/packages/p/python-libtmux/testing/amd64/74916704/
and
https://ci.debian.net/packages/p/python-libtmux/testing/armhf/74917824/
for examples. On other architectures they did not fail and also the
history of autopkgtests (e.g. on amd64
https://ci.debian.net/packages/p/python-libtmux/testing/amd64/) suggests
that those tests fail randomly.

Cheers
