New description:

 While trying to perform any ''plot'' command (batch or interactive) in
 ngspice 26 - see § 17.5.43 in
 [http://ngspice.sourceforge.net/docs/ngspice26-manual.pdf ngspice's
 manual] -- the following error is shown:
 {{{

 }}}

 To reproduce download the attached ''simple.cir'' file and run ''ngspice
 simple.cir'' (leave the interpreter using ''quit'', ''exit'' or !^D).
