[X2Go-User] Segfault with rstudio and x2goclient on Fedora 26

[Norman Gaywood]

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.
