[X2Go-User] Segfault on some applications

[Thackeray, Neil L]

This is a list of packages that were upgraded. I wonder if there was a change in libc that is causing the problem?

I wasn't specific enough, it is 16.04.1. I've installed on a test computer as well and the problem replicates. This problem didn't happen until I did an apt-get dist-upgrade today.

Distributor ID:	Ubuntu
Description:	Ubuntu 16.04.1 LTS
Release:	16.04
Codename:	xenial

      I am using 16.04.1 LTS and do not have this problem.  If you are just on 16.04 and not 16.04.1, I would suggest upgrading.  I had a lot of problems with 16.04 as well.  I think it was released a little ahead of being ready for primetime.

I've completely lost KDE, which I see is a known issue, but for some reason now Firefox and many other applications don't work. I even tried gnome-calculator and it doesn't work now, but LibreOffice does. I'm not sure if it's because of the graphical toolset used or not. The most important app not working for us is Eclipse. All of the applications that don't work function fine with an exported X session, but there is just something in X2go that is keeping it from working.
