[TYPO3] bug in copy page?

[Nagita Karunaratne]

Hi,

Is there some bug in the copy page functionality? Or is it my system?

I am getting this error when I try to copy and paste a page (into and 
after).

---------------------------------------------------------------------------------------------
Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL 
result resource in /var/www/typo3_src-4.1.2/t3lib/class.t3lib_db.php on 
line 796

Warning: Cannot modify header information - headers already sent by 
(output started at 
/var/www/typo3_src-4.1.2/t3lib/class.t3lib_db.php:796) in 
/var/www/typo3_src-4.1.2/typo3/tce_db.php on line 225

---------------------------------------------------------------------------------------------


But the copy process works despite this error.

Thanks.
