Hello
I just upgraded my Ubuntu setup with a normal apt-get upgrade and nx-agent version 2:3.5.99.16-0~201803162252~ubuntu16.04.1 was installed. The segfault problem went away, X2Go works again "as specified".
BR,
Kalle

I've got several users reporting seg faults in nxagent
Mine occur when moving my x2goclient window from one screen to another. Simple resizing seems OK.
Not sure if this is the same for all my users though.
Seems to be happening after these updates:

It does not seem to be possible to roll back.

I'm thinking it may be the latest update to libNX_X11 (a few days ago) But the x2go repo does not contain old versions, so I can't test the downgrade.
