So I've updated dev to the latest again 3.5.99.15-0.0build1.1.git20180308.2971.main.fc27
And I seem to get an nxagent segfault every time I move the session window into another screen. Same version in production and it was stable for a few days now. I could move it across screens. I suspended and resumed several times. But, after logging out of production and logging back in again, I'm back to segfaulting when moving across screens. It's a very strange problem :-( Executive summary: The segfault on connect I have not reproduced. But its been reported by several of my users. I have around 50 logged in users at the moment. The login segfault only happens to very few (5/6). Some of them seemed to be working now. The move across the screen segfault has happened to 3 users (including me) and all have been linux clients (Fedora I think). The move across screen segfault seems to go away sometimes for undermined reasons.
