I thought it was a typo in your other mail. zprofile is the startup file 
for the zsh shell. It's corresponds to the .bash_profile for bash.

But I really mean .xprofile. If it does not exist, create the file and write

# all Profile beim Start des Displays Managers öffnen
source ~/.bash_profile

into it.
Also, remove that line from the zprofile.

Try again after doing what I wrote above.

No, it does not. Unless you changed it in your system config, it's the 
same every other guix user has on their system.

This looks good: You started a login shell with an empty environment, 
(it means when it started, no guix-profile was activated), and the 
commands icecat and chromium were found.

The reason they printed errors is because the couldn't initialize the 
connection to the window manager, which is necessary for graphical 
applications. The couldn't connect because the environment variable 
DISPLAY was not set (since env - removed it for the shell and it's child 
processes).

So, if icecat and chromium are not installed system wide but only in one 
of your custom profiles, it means they must have been actived by the 
login shell you started. So your .bash_profile seems to work.
