It looks like columns isn't defiened becuase of the indentaion.  Also
are you sure there is a 'columns' ?  

I know you define it in the init routine to be and empty [] but what
happens if the calling routine passes a None to the columns variable? 
Then there is no columns variable (I think).

Try doing a print columns just before the error to see exactly what
columns is.
