tsclient fails repeated remote desktop after first connection

Binary package hint: tsclient

The first rdp connection to a windows machine succeeds, but subsequent attempts to connect fail. The error reported is:

Autoselected keyboard map en-us disconnect: Internal licensing error.

Deleting the .tsclient folder from the home directory and then restarting tsclient is the only way I've found for subsequent connections to succeed.
