mailsystem_html_to_text() function did not return any text [#1494910]

HTML MAIL feature is not working correctly. Some of the users are not receiving email. It is important as these are the account confirmation emails.

Error Message : "The mailsystem_html_to_text() function did not return any text. Please report this error to the Mail system issue queue."

I am trying to send a HTML email. The message body has some HTML Code. I am getting the above error and email is not sent to the user.

// Retrieve the responsible implementation for this message.
$system = drupal_mail_system($module, $key);

// Format the message body.
$message = $system->format($message);

// Send e-mail.
$message['result'] = $system->mail($message);

Please do this:

Apply the attached patch to your Mailystem module directory.
Trigger the sending of an account confirmation email.
Check your /admin/reports/dblog page for a message with type = mailsystem.
When found, attach the message to this issue.

Thank you.

I've just added the patch and will await the next email to go out. When that happens I will upload the message for you.

I am using php 5.4. Also your patch doesn't function. I had to tweak it to read:

$text_temp = trim($text);
$string_temp = trim($string);

if (empty($text_temp) && !empty($string_temp)) {
  //throw watchdog error.
}

I was getting a cannot use return value as write context errors.

Is this dead? Because people are getting empty emails from us! Please, we've tried just about everything. I've even modified some of the code to try and avert this...

'it seems' that you need mail_system variable to be setup as (use /admin/config/system/mailsystem to setup).

the site-wide default is DefaultMailSystem
the YOUR-MODULE was created from the 'new setting' field set.
1. module: YOUR-MODULE
2. key: YOUR-KEY
The htmlmail was created in the "new class' field set. With both 'format' and 'mail' set to 'HTMLMailSystem'

a Variable dump of mail_system:

Array
(
    [default-system] => DefaultMailSystem
    [YOUR-MODULE_YOUR-KEY] => HTMLMailSystem
    [htmlmail] => HTMLMailSystem
)

then drupal_mail works (yes, 'htmlmail' even though you expect to use YOUR-MODULE):

if (drupal_mail('htmlmail', 'YOUR-KEY', $client_to, language_default(), $client_params, 'noreply@example.com', TRUE)) {
 //if mail is sent..
} else {
 //if mail not sent..
}

=============

follow up: my third list point seems not to set it.. sending a test [ /admin/config/system/htmlmail/test ] seems to set var for mail_system([htmlmail] => HTMLMailSystem )

themed mail tpl to use:
htmlmail--htmlmail--YOUR-KEY.tpl.php

You can see my setup for the mailsystem. It's been working really well for at least a year. It just started randomly sending blanks to people. I have the following installed:
