@lacombar, we need more detail in order to reproduce this.

The BZR_EMAIL environment variable in the test is supposed to prevent exactly this failure mode:
https://github.com/breezy-team/breezy/blob/9d812602812df574beb63ee13005f56f600aecb8/breezy/config.py#L544-L560

It isn't clear to me why that isn't having the intended effect for you. What version of the bzr command are you using? What relevant configuration do you have on your machine and/or in your environment?
