GNOME Bugzilla – Bug 766573
Uses deprecated libunique
Last modified: 2017-07-02 17:45:18 UTC
The libunique library is in maintenance mode and its usage is strongly discouraged [1]. Applications should use the GtkApplication class provided by GTK+ 3.0. Under [2] you will find a porting guide for migrating from using Unique to GApplication or GtkApplication. [1] https://wiki.gnome.org/Attic/LibUnique [2] https://developer.gnome.org/gtk3/3.20/gtk-migrating-unique-GtkApplication.html
This has been done in filemanager-actions 3.4, the replacement for nautilus-actions.
