[TYPO3-english] sr_feuser_regsiter email error at the time of update profile

[PIT Solutions]

Hi List,

I am using typo3 version 4.7.14 and my sr_feuser_register version is 3.0.1.
At the time of creating a profile using sr_feuser_register, there is no problems.
But in the case of updation of a profile, the frontend user got an error at the final stage;

The error is;

Uncaught TYPO3 ExceptionAddress in mailbox given [] does not comply with RFC 2822, 3.6.2. 

Swift_RfcComplianceException thrown in file
/typo3/contrib/swiftmailer/classes/Swift/Mime/Headers/MailboxHeader.php in line 308.

00238:       $this->_assertValidAddress($address); 
00239:       $actualMailboxes[$address] = $name;
00240:     }

/typo3_src-4.7.14/typo3/contrib/swiftmailer/classes/Swift/Mime/Headers/MailboxHeader.php:

00094:   public function setNameAddresses($mailboxes)
00095:   { 
00096:     $this->_mailboxes = $this->normalizeMailboxes((array) $mailboxes); 
00097:     $this->setCachedValue(null); //Clear any cached value
00098:   } 


I don't know why its happened. And I got no emails at the time of updation due to this error. But the profile is updated correctly.

I've also given the email address as "test at myemail.com", and with using quotes. But still got that error.
Please help me.

Thanks in advance;
    Arun Chandran.
