This is caused by the way we handle dialogs from nxagent. Currently, every
dialog (wrongly) spawns x2gosuspend-session for every message the agent wants to
show.

nxagent sends a KILL SESSION dialog when close_session is executed for
non-persistent sessions (like shadow sessions), but the default handler
x2gosuspend-session that is set via NX_CLIENT is x2gosuspend-session, which is
called and fails to suspend the session (since session suspension doesn't make
sense or works with non-persistent sessions.)

While the general goal should be to relay messages to the client side one day,
currently I want a small wrapper script on the server side which handles
server-side events in a better way.

Thus retitling this bug report.
