Open Basedir Restriction Error Refers To Another Username

One of my users...let's call him "fictional" is getting the following error message:

---------
Warning: Unknown(): open_basedir restriction in effect.
File(/home/fictional/public_html/blablaja/index.php) is not within the
allowed
path(s): (/home/hurz/:/usr/lib/php:/usr/local/lib/php:/tmp) in Unknown
on line 0
---------

The strange thing is that the error message refers to another user on my system...named "hurz". Why does it refer to this other username? I looked at the virtual host in httpd.conf for user "fictional" and everything seems alright there:

<IfModule concurrent_php.c>
php4_admin_value open_basedir "/home/fictional:/usr/lib/php:/usr/php4/lib/php:/usr/local/lib/php:/usr/local/php4/lib/php:/tmp"
php5_admin_value open_basedir "/home/fictional:/usr/lib/php:/usr/local/lib/php:/tmp"
</IfModule>
<IfModule !concurrent_php.c>
<IfModule mod_php4.c>
php_admin_value open_basedir "/home/fictional:/usr/lib/php:/usr/php4/lib/php:/usr/local/lib/php:/usr/local/php4/li$

<IfModule mod_php5.c>
php_admin_value open_basedir "/home/fictional:/usr/lib/php:/usr/local/lib/php:/tmp"
