Package: python3-pip Followup-For: Bug #847918 Hi,
this report can be closed. As could've been deduced from the error message, the crash was rather due to a local version conflict between pip and Setuptools. It appears I had accidentally updated my system version of the latter, instead of a user or pyvenv installation. So this is not a bug.
