I was not able to reproduce this on Python 3.7, only with 3.8.

Comment 1 Miro Hrončok 2019-10-10 09:36:12 UTC
Upstream bug: https://bugs.launchpad.net/bugs/1844684

As a workaround, we can turn off the C extension modules.

Comment 3 Miro Hrončok 2019-10-11 15:42:31 UTC
The workaround has been pushed. Keeping this open to track the actual solution. Removing the high severity flag.

Comment 4 Miro Hrončok 2019-10-19 09:42:17 UTC
Fixed properly.
