python-urwid-1.3.0 fails to build on x86_64 during the
"AsyncioEventLoopTest" test with the error "KeyError: '5 is not
registered'". It has failed repeatedly for some time now. It fails in
the same way when updated to python-urwid-1.3.1.

I looked for interesting changes made between the last successful build
and the first failing build. Notably, this range includes the upgrade
from python-3.3.5 to python-3.4.3 (08c04509). Asyncio was integrated
into the Python standard library in 3.4 — previously it had been an
external library. [0] Our python-3.4.3 package passes its 'test_asyncio'
test, FWIW.

I entered the failed build tree and successfully ran the tests using the
python-3.4.3-7 [1] installed by Debian Stretch. That only tells us so
much, but I think it does indicate either a bug in our python-3.4.3, or
some problem with python-urwid caused by the unfamiliar Guix build
environment.

Here's the hydra.gnu.org page:

Here's the failing part of the build log:
