Description of problem:
I think this commands should return human-readable message when error raises.

$ wallaby -H xulqrxy-node01 -U guest -P guest cluster-remove-jobserver name='hasched1'
localhost password: 
fatal:  undefined method `each_index' for {}:Hash

This is bug was found during testing 833308 so there is no ~/.ccs directory and no password entered to ricci.
