Code review comment for lp:~junrrein/pantheon-files/fix-1069275

I tried this:

MarlinViewPropertiesWindow *properties = marlin_view_properties_window_new (file_list, view, GTK_WINDOW (view->details->window));
g_signal_connect (properties, "destroy", G_CALLBACK (g_list_free), file_list);

But now Files segfaults when closing the Properties window.
Unfortunately, I don't know what to do now. Need help guys.
