Package: x2goserver Version: 4.0.1.19-0~1064~ubuntu16.04.1

When I try to run the virt-manager application from an x2go session in single application mode, the entire x2go session appears to crash and is abruptly disconnected. I am inclined to blame this problem on x2go and not virt-manager because of the following:

• virt-manager runs just fine without issue under these conditions:

  • Running under x2go when using a window manager like jwm or icewm.
  • Running under tightvncserver with xrdp.
  • Regular X11 forwarding over SSH of virt-manager using MobaXterm. It is only when it is used with x2go in single application mode that there are problems.

• Even if it is a virt-manager issue, it seems to me that a misbehaving application should not cause the entire x2go session to die.

Steps to reproduce:

1. NOTE: Tested from within an Ubuntu 16.04 LXD container on Ubuntu 16.04 host.
2. Install virt-manager package; I used latest 1:1.3.2-3ubuntu1.16.04.1
3. Install X2Go Server as per http://wiki.x2go.org/doku.php/doc:installation:x2goserver I used 4.0.1.19-0~1064~ubuntu16.04.1
4. Also you should have some terminal installed, e.g. rxvt-unicode-256color package.
5. On a client Windows PC running X2Go Client 4.0.5.0, set up connection, noting the following: a. Session type: pick Single application, and "Terminal" from drop-down.
6. Go ahead and connect. At the terminal, type: virt-manager

Expected behavior: virt-manager should open without incident.

Actual behavior: The rxvt console window disappears. virt-manager does not open. My connection is disconnected and I get the following error:

X2Go - 50

The connection with the remote server was shut down. Please check the state of your network connection.

OK
