[Mediawiki-l] Warnings in non-english Language page

[Selva]

Hi,
I am running MediaWiki 1.1.0 with LanguageTa.php.
I am able to get the page up, but get the following warnings at the 
page:
----
Warning: session_start(): Cannot send session cookie - headers already 
sent by (output started at 
/usr/local/apache/htdocs/wiki/LanguageTa.php:375) in 
/usr/local/apache/htdocs/wiki/Setup.php on line 53

Warning: Cannot modify header information - headers already sent by 
(output started at /usr/local/apache/htdocs/wiki/LanguageTa.php:375) in 
/usr/local/apache/htdocs/wiki/OutputPage.php on line 208
----
These warnings repeat a few more times. Help?
Should I pick up the 1.2.0rc2?

thanx. Selva.
