I think I found a fix. From this thread:

http://www.bioinformatics.org/pipermail/bio-linux-list/2015-March/000804.html

Where it says:

As shown, I moved aside those rstudio Qt libraries on my Fedora 26 and Centos 7.4 x2goservers.
Also installed qt5-* on the f26 and centos 7.4 x2goservers

After that connecting from my Fedora 25 x2goclient, rstudio did not segfault and seems to work.

I have a few installations of rstudio

https://www.rstudio.com/products/rstudio/download/#download

running on Fedora 26, Centos 7.4 and Red Hat Enterprise 7.4 x2go server:

x2goserver-4.0.1.20-2.fc26.x86_64
x2goserver-4.0.1.20-1.el7.x86_64

With the these two x2goclient on Fedora 26:
x2goclient-4.1.0.0-1.fc26.x86_64
x2goclient-4.1.1.0-1.fc26.x86_64

rstudio will segfault on startup.

Any other x2goclient I've tried, 4.1.0 on Windows and 4.0.5 on Mac, rstudio works no problem.
Also doing "ssh -Y" to the hosts running x2goserver, rstudio starts with no problem.

rstudio has worked in the past (maybe several months ago). Perhaps I was using Fedora 25 then. So I'm guessing that it's something to do with the x2goclient on Fedora 26.

Any ideas?

On trying to start rstudio inside an x2gosession the segfault looks like:
$ rstudio
