4.0.1pl2 -> 4.0.2 = can't execute script

hi.

i've just upgraded from 4.0.1pl2 to 4.0.2 .
now, when i try to start a php-script i get an error.

Warning: Unable to access
/home/sites/domain.com/home/sites/domain.com/www/test--.php4 in Unknown on
line 0
Warning: Failed opening '/home/sites/domain.com/www/test--.php4' for
inclusion (include_path='.:/usr/local/lib/php') in Unknown on line 0

the filename 'test--.php4' is correct. but the directory in the first line
is wrong.

in the apache's virtualhost-tag i've the following:

[..]
 php_admin_value open_basedir   /home/sites/domain.com
 php_admin_value doc_root       /home/sites/domain.com
[..]

and in the php.ini file this:

[..]
doc_root        = /home/sites
open_basedir    = /home/sites
[..]

btw: i'm running apache 1.3.12, php4 as dso-module

v4.0.1pl2 worked without problems with this configuration.

thanks in advance.

greetings,

daniel
