In my case there were two instances of a key with the value dc545090-f8f4-11e5-94f1-000000000000. \r\n\r\nBooting up a scylla with a clear data directory and connecting with the c# driver works and creating a workspace works fine but after dropping the key space a duplicate value appears. This causes the c# driver to fall over because it stores the result of the map column in a Dictionary which cannot have duplicate key values so throws an exception.
