[Typo3] Broken rootline

[tapio]

Hi

I took tables 'pages', 'tt_content' and 'sys_template'
from another installation.

Why I got:

Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL 
result resource in /home/int2000/23329/html/t3lib/class.t3lib_db.php on 
line 741

Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL 
result resource in /home/int2000/23329/html/t3lib/class.t3lib_db.php on 
line 741


Error!

The requested page didn't have a proper connection to the tree-root!
