Bug#815344: preseeding: empty tasksel not possible

[John Wyzer <john.wyzer@gmx.de>]

Package: debian-installer
Version: 20150422+deb8u3
Severity: important
Tags: d-i

I used the current netboot.tar.gz for debian jessie from http://ftp.debian.org/debian/dists/jessie/main/installer-amd64/current/images/netboot/ to create a pxe based preseeded installation.
Everything works fine except the tasksel configuration.
I don't want to execute any of the tasksel tasks.
Whatever I do, the installer starts to install about 1500 packages including Xorg.

I tried
	tasksel tasksel/first   multiselect
then I added
	tasksel tasksel/skip-tasks  string standard 
which I had in a working minimal configuration for wheezy.

Nothing helped.

I ran a normal manual install and dumped the configuration with 
	debconf-get-selections --installer
The output contained the line
	d-i     tasksel/first   multiselect     
which is different from what is documented for the installer - but I tried that, too.

Then I added all the tasks from "tasksel --list" to the skip-tasks line mentioned above....

Still a full desktop installation.


Is there any way to install a really minimal configuration via preseeding in jessie?
