open nautilus at boot time (command)

[René]

hello
i do load a specific folder at GDM login.
means, nautilus pops automaticaly up with this folder when the user  
settings get loaded.
this window (of nautilus) comes up on the display (of course), BUT how to  
do it, that it minimizes itself to the taskbar at the bottom.
the command right now is: nautilus /home/my-user/specific-folder
what i have to add? can anybody help?
thank you,
René
