Thanks again, Christian!
I turned off apparmor using /etc/init.d/apparmor teardown and restarted the
vsmserver.
As soon as I succesfully connect via thinlinc from a Ubuntu 10.10 desktop to the
thinlinc server running Ubuntu 10.04 LTS desktop in a VMware virtual machine, I get:

Any ideas where the

comes from every two seconds?
