Hi Peter, I have been playing around with a fresh install of Ubuntu GNOME this morning, and I still cannot replicate your issue with Gramps 4.2.2. I couldn't use Kubuntu because there is an installer bug in Virtual Machines at the moment.
During the install I choose English, then my location in Europe, then my keyboard (again a special European one). I end up with US English as default. Then I do $ sudo dpkg-reconfigure locales, and choose only en_NZ.UTF-8, and set it as the default. After logging out, and logging back in, I get: $ printenv | grep LANG LANG=en_NZ.UTF-8 LANGUAGE=en_US:en gramps comes up without error. So I manually set LANGUAGE as you have: $ LANGUAGE=en_NZ:en $ export LANGUAGE $ printenv | grep LANG LANG=en_NZ.UTF-8 LANGUAGE=en_US:en Gramps still comes up without error. How did you go about selecting your language? Can you please give me the result of "$ locale -a"? ** Changed in: gramps (Ubuntu) Status: In Progress => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1511917 Title: Gramps detected incomplete GTK installation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gramps/+bug/1511917/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
