[TYPO3-english] class.t3lib_htmlmail.php ERROR - canary mismatch on efree() - heap overflow detected

Hi,

I'm getting this error with the sr_feuser_register subscription page.

Running TYPO3 4.3, any clue what it really means ?

[Thu Feb 04 11:34:17 2010] [error] [client 91.203.96.55] ALERT - canary

file '/var/www/site/typo3_src-4.3.0/t3lib/class.t3lib_htmlmail.php', 
line 730)

Thanks for your feedback,
Daniel
