solved my gimp example problem

[Mono <mono _at_ posteo _dot_ de>]

Hallo Torsten,

thanks again for yesterdays help!
I solved the problem. Especially your hint executing autostart from 
command line revealed:

[~/.config/herbstluftwm]$ ./autostart
[~/.config/herbstluftwm]$ load: rename: Tag "default" not found
Missing ) or arguments
load: Error while parsing!

oops. well I tracked it down to the following part in my autostart. The 
original says:

function hc() {
    herbstclient "$@"
}

mine said:

function hc() {
    cmds="$cmds , $@"
}

and further down just before "find the panel":

herbstclient chain $cmds&

Um, I remember to have taken those modifications from some forum post, 
somewhere, blindly. I cant even remember what it is supposed to do, but 
indeed it broke the autostart tag-layout loading.

best regards
Mono
