ADMIN_USER may not be empty

Hallo,
I tried to use phpwiki with postgresql but I got this error message.
In /etc/phpwiki/config.ini there is an entry for ADMIN_USER.
So I do not understand the following error message:

Fatal Error:
lib/IniConfig.php:668 Error: ADMIN_USER may not be empty. Please update your
configuration. 
Notice: "missing config setting for ADMIN_USER" (...repeated 2 times)

lib/IniConfig.php:668 Error: ADMIN_USER may not be empty. Please update your
configuration. 

I am using phpwiki under Debian-Lenny and I configure with
dpkg-reconfigure phpwiki and I select postgresql.
After finishing reconfigure I adapt the DB-URL in the config.ini and run
psql-initialize on the Postgresql-Server to build the tables.
It gaves a few errors but it seems to work.

And when I call the wiki start page after this I got this error message.

Thanks for any hints.

Ciao 
  Peter Schütt
