[wp-testers] Importing from 2.9 version

[wp@peterwongpp.con]

Dear all,

This is my first time posting in the list.

I just installed 3.0B1 and inported the posts and categories etc.  
However I found some warning message like this.

Warning: mysql_real_escape_string() expects parameter 1 to be string,  
array given in \wp-includes\wp-db.php on line 772

And there will be two lines of the same sentence appeared whenever it  
is there.

I know that warning is not like fatal error, but we should get rid of  
them too, right?
