This bug is more of a bug with types.  I think that what you're looking at 
is similar to another problem that I noticed recently (but I forgot to ask 
about/report here):

octave:1> a = {1 2};
octave:2> class(a)
ans = cell
octave:3> class(a{:})

the second gives the help for class.  In reality, both my and your errors 
should give an error that the function is given too many input arguements.
