Package: x2goserver-x2goagent
Version: 4.1.0.4
Severity: grave

I am running two openSUSE Tumbleweed machines, both with x2goserver
4.1.0.4 (from Git commit gaef470fe) and x2goclient 4.1.2.2, and often
use X2Go in single application mode to connect between them.  Following
a Tumbleweed update on the client machine (from 20200708 to 20200724),
the X2Go connection now disconnects whenever I copy text into the
clipboard on the local machine and then paste it into the remote
machine.  The following error message appears in the system log of the
remote machine:

2020-07-28T11:16:12.479151+02:00 butterfield systemd-coredump[18451]:

The Tumbleweed update included some changes to X11/KDE packages that
broke at least one other application (most notably emacsclient) so
perhaps this is also the case here.  (Though according to the openSUSE
bug triagers, the breakage is the other application's fault.)  I am
running KDE on the local machine; I haven't tested if the problem is
reproducible with a different desktop environment.

Detailed steps to reproduce:

1. On the local machine, configure an X2Go connection to a remote
machine to launch a single application such as xfce4-terminal or
konsole, and then launch that connection.

2. On the local machine, use the mouse to select some text in a locally
running application, which will copy it to one of the clipboards.
(Alternatively, copy it to the other clipboard with Ctrl+C or Ctrl+Ins.)

3. On the local machine, switch to the remote window and paste the
contents of the clipboard by middle-clicking. (Alternatively, paste the
other clipboard with Ctrl+V or Shift+Ins.)

At this point the X2Go session will disconnect and the above-noted error
message gets written to the remote machine's system log.
