Lighttpd

Hi. I get a segfault with a simple configuration file (which is a simplified version of what I actually use):

var.basedir  = "/var/www/localhost" 
var.logdir   = "/var/log/lighttpd" 
var.statedir = "/var/lib/lighttpd" 

server.modules = (
    "mod_webdav" 
)

include "mime-types.conf" 

server.username      = "lighttpd" 
server.groupname     = "lighttpd" 

server.document-root = var.basedir + "/htdocs" 
server.pid-file      = "/var/run/lighttpd.pid" 

server.errorlog      = var.logdir  + "/error.log" 

$HTTP["url"] =~ "^/a/" {
        dir-listing.activate = "disable" 
}
$HTTP["url"] =~ "^/b/" {
        dir-listing.activate = "disable" 
}
$HTTP["url"] =~ "^/c/" {
        dir-listing.activate = "disable" 
}
$HTTP["url"] =~ "^/d/" {
        dir-listing.activate = "disable" 
}
$HTTP["url"] =~ "^/e/" {
        dir-listing.activate = "disable" 
}
$HTTP["url"] =~ "^/f/" {
        dir-listing.activate = "disable" 
}
$HTTP["url"] =~ "^/g/" {
        dir-listing.activate = "disable" 
}
$HTTP["url"] =~ "^/h/" {
        dir-listing.activate = "disable" 
}

# vim: set ft=conf foldmethod=marker et :

# lighttpd -D -f lighttpd.test.conf && echo "ok" 
Segmentation fault

The segfault does not happen if I remove at least one of $HTTP["url"] directives, or if I remove mod_webdav. I run gentoo on a 32 bit arm vps. Lighttpd version is 1.4.54.
