[X2Go-User] x2goclient segfault with ubuntu 18.04 kde

[Michael]

Hi

I'm getting a segfault on kde (at the moment it's the neon.kde.org packages,
but before it was kubuntu) on ubuntu 18.04.

How do I debug the crash or better still, how do I fix the crash?
I saw a bug about x2goserver and kde, it could be related i guess.
https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=1312

x2goclient version 4.1.2.1 (I updated to the debs supplied by x2go after
the ubuntu supplied version crashed)
the server is an centos 6 it was epel 4.0.1.20-1.el6.i686 but I upgraded it
to the packages supplied by x2go x2goserver-4.1.0.2

Also, is there a snap available? google says no.
