Not a bug in fourier --- it appears to be due to this bug in limit.

At this point I don't know anything else about it.

Thanks, Robert.
The same limit error occurs in ver. 5.19.1
and 5.19.0.
Ver. 5.18.1 appears to have the last good version
of limit, since the behavior is:
-------
Maxima 5.18.1 http://maxima.sourceforge.net
Using Lisp GNU Common Lisp (GCL) GCL 2.6.8 (aka GCL)
..
(%i1) display2d:false$
(%i2) limit ((sin(n*x) - n*x*cos(n*x))/n^2, x, %pi);
(%o2) sin(%pi*n)/n^2-%pi*cos(%pi*n)/n
(%i3) declare (n,integer)$
(%i4) limit ((sin(n*x) - n*x*cos(n*x))/n^2, x, %pi);
(%o4) -%pi*(-1)^n/n
------------
Is this a known bug in version 5.19.2?
