Finally I found the solution in this old thread:
http://mail.gnome.org/archives/gtk-list/2004-October/msg00002.html
It says to:
"Put your [...in my case: "statusbar"] in an eventbox and then change 
the background of the eventbox."

My Xfc application that didn't present the problem was using a Gtk 
EventBox itself.

Thanks ;-)
