"Call to a member function addRecipient() on boolean" when create new user

[Sulpher]

Steps to reproduce the issue

After updating Joomla to 3.6.0 I started to create a new user. As a result, I get this error message:

An error has occurred.
0 Call to a member function addRecipient() on boolean

It is happens with PHP 7.0.8.
I turn sever on PHP 5.6 and repeat creating new user. As a result, I get another error:

The mydomain.com page isn’t working
mydomain.com is currently unable to handle this request.
HTTP ERROR 500

But all users have been created.

Expected result

There shouldn't be such error message.

Actual result

Described above.

tried with php 7.0.8 and can't reproduce the issue.

It's a result of #9881

You'll only get that type of error if you feed invalid data into JMail. In 3.5.1 it was throwing Exceptions, 3.6 tries to catch them in JMail and consistently return boolean false on an error case versus blissfully discarding any errors.

Long and short, validate your email addresses are valid before calling any method in JMail or PHPMailer which accepts an email address as an argument.

@mbabker @PhilETaylor thanks for the tip which way to go. I just been checked out Mail Settings in Global Configuration and found it's unable to save settings. Browser console shows this:

JQMIGRATE: Migrate is installed, version 1.4.1
2sendtestmail.js:6 Uncaught ReferenceError: sendtestmail_url is not defined

Sorry for reporting about another issue(?) here.

Misprinted. I unable to send test mail.

Clear Browser cache (Ctrl+F5) and then save

Ahh..... My fault! Sending test mail works now after cache clearing. :-)
