XDM authorization problem with xfprint

[Bernhard Walle]

Hello,

I recognized that dragging a file to the xfprint icon does not work. So
I tried to run on console and I got:

        [~/Eigene/notizen] $ xfprint-manager file.txt
        Xlib: connection to ":0.0" refused by server
        Xlib: XDM authorization key matches an existing client!

        (xfprint4:5717): Gtk-WARNING **: cannot open display:  

That worked:

        [~/Eigene/notizen] $ xfprint4 file.txt

And after xhost +localhost the xfprint-manager file.txt worked, too.
What went wrong?

Regards,
Bernhard
