Conflict with plugin "Register Plus Redux" (own wp_new_user_notification)

[marcopenhacking]

When "BrowserID-Wordpress" is active "Register Plus Redux" writes this message is shown on the plugin page:

There is another active plugin that is conflicting with Register Plus Redux. The conflicting plugin is creating its own wp_new_user_notification function, this function is used to alter the messages sent out following the creation of a new user. Please refer to radiok.info for help resolving this issue.

It disappears when "BrowserID-Wordpress" is deactivated.

Mail notifications of "Register Plus Redux" are not sent while "BrowserID-Wordpress" / "Mozilla Persona" is activated.

Wordpress 4.1, Mozilla Persona 0.50, "Register Plus Redux" Version 4.0.3

[Erudition]

I, too, am attempting to use these two plugins.
