It's missing and thus breaks updating to GNOME > 3.18.0. Given that you're a user of experimental it is expected that you know your way around both looking up developer information and fixing any issues that might arise from using packages from experimental. Developer information page for gtk+3.0 is available at: http://packages.qa.debian.org/gtk+3.0 Please see the links section where you'll find an "exp" link for buildd information. Hope this helps. Have a nice day. Regards, Andreas Henriksson
