where I am trying to plot out the last column using a histogram plot in
gnuplot, org fails with an error:

Debugger entered--Lisp error: (wrong-type-argument sequencep 3)

where the last function invoked was "orgtbl-format-line(3)".

The trace is attached.  This is with org up to date as of a few minutes ago.

The trace shows that the column has been extracted exactly as I
wish.  However, it would appear that the function may expect a sequence
and not just a single element?  If I try to extract more than just one
column, everything is fine (although obviously the gnuplot directives
need to change...).

thanks,
eric
