From X2Go BTS:

Package: x2goagent
Version: 3.5.0.31-1.el6

When I disconnected from a windows client, I lost my session. This is the
result in the server at the time of the disconnect. It does not happen
every time, just some times when I disconnect. I can re-connect fine with a
new session, but the running session is lost.

You may be able to get abrt to recognize the key for nxagent by reinstalling it:

yum reinstall nxagent

assuming it is actually a signed package. Not sure where it's coming from as 3.5.0.32-3.el6 is what is current from EPEL. If not signed, there should be a config somewhere in /etc/abrt* to tell it to keep coredumps from unsigned packages.

I vote for closing this, we have improved libX11 a lot since Feb 2016...
