I figured out that disabling the Logo elsewhere called splashsceen (in the file /etc/libreoffice/sofficerc set Logo=0) does the job. funnily enough this really cancels all problems (no more messing around with bamf or lo-menubar). So the major bug is about the splash-screen messing up something in the case "open a document from desktop/nautilus"
