Bug in ColVis?

JQ_Noob

I'm using DataTables 1.8 and when I call oTable.fnSetColumnVis(i, false) on the last and only visible column in the grid, it gives me an error:
"Invalid Argument" in JQuery.DataTables.Min.JS. It works fine until when there is only 1 column left, hiding the last column gives an error. Is this a bug or am I doing something wrong? Thanks.
