pip3 launches the KDE Wallet Service

[Tom Cook]

Since upgrading to 21.04 (python3-pip package version 20.3.4-1ubuntu2), every time I run `pip3` I get the KDE Wallet Service starting and showing a window, saying:

The application '/usr/bin/pip3' has requested to create a new wallet named 'kdewallet'. This is used to store sensitive data in a secure fashion. Please choose the new wallet's type below or click cancel to deny the application's request.

I'm given a choice of blowfish or GPG.

Pressing cancel seems to have no negative consequences for the package install.

Note that this has been reported upstream: https://github.com/pypa/pip/issues/8090

It's not obvious from a quick look through the history of that ticket whether it has been properly fixed.

A workaround is to `export PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring`.

Status changed to 'Confirmed' because the bug affects multiple users.
