[Pkg-xfce-devel] Bug#568759: I see this also

[lord licorice]

I can confirm this as well. When xfce4-clipman is running, mousepad
won't close after copying text. I have to quit, wait a few seconds,
and quit again for the window to close. I get

(mousepad:13648): Gtk-CRITICAL **: gtk_main_quit: assertion `main_loops != NUL

in the console when I quit for the second time (which works). Moving
mousepadrc doesn't correct the problem.
