I'll confirm this as well. It does the same thing here. And I'm not sure if this is actually related but nxagent will also die in exactly this manner if I attempt to use the bi-directional clipboard feature and paste clipboard data into the session from the client's OS in desktop mode. It happens regardless of whether I use x2go or NX to create a session.
I can confirm this also. ALso the clipboard problem.
Marking this one as obsolete, with current versions I run single apps and use clipboard to/from a desktop session without problems. Don't hesitate to reopen if the bug still happens for you!
