[horde] DB error after updating mysql

[Thomas Nowotny]

Hi!
I get the following error, after updating my mysql database to
mysql-4.0.15-9 on a SUSE Linux 9.0.

---------
Notice: Undefined index: socket in /usr/share/php/DB/mysql.php on line 108

Warning: Cannot modify header information - headers already sent by
(output started at /usr/share/php/DB/mysql.php:108) in
/srv/www/mail/horde/index.php on line 59
---------

With mysql I can connect to the database without problems and I can slso
use tools like phpmysql on it. But I still get the error at top. Any hint?
