lighttpd forum lighty > Lighttpd claims but fails to start

Hello All!
We run a small server on Debian Testing (this is bad, we know ^^) and 
today, we possibly encountered a bug.

The server has 3 users "host", so 3 homes and www/ in each one:
/home/host1/www, /home/host2/www and /home/host3/www

lighttpd.conf includes several vhosts as follow:

$HTTP["host"] =~ "^host1.net$" {
        server.document-root = "/home/host1/www"
        server.errorlog = "/home/host1/error.log"
        accesslog.filename = "/home/host1/access.log"
        server.error-handler-404 = "/e404.php"
}

$HTTP["host"] =~ "^host2.net$" {
        server.document-root = "/home/host2/www"
        server.errorlog = "/home/host2/error.log"
        accesslog.filename = "/home/host2/access.log"
        server.error-handler-404 = "/e404.php"
}

$HTTP["host"] =~ "^host3.net$" {
        server.document-root = "/home/host3/www"
        server.errorlog = "/home/host3/error.log"
        accesslog.filename = "/home/host3/access.log"
        server.error-handler-404 = "/e404.php"
}

www-data is in host1, host2 and host3 groups

If say /home/host2 has wrong permissions (700 recursively for instance, 
lighttpd can't access to access.log and error.log), and /home/host3 have 
right permissions (770 in this case),
/etc/init.d/lighttpd start
lighttpd claims to start but doesn't actually.

When removing the $HTTP["host"] =~ "^host3.net$" , lighttpd reports the 
error stating that it can't access to access.log and error.log and fails 
to start.

Can someone please confirm that possible bug in this version of 
lighttpd?

$ apt-cache policy lighttpd
