SYMPTOM:
--------------------------
"Unexpected Field Value" error is reported when using
Mechanize::follow_link() method.
ROOT CAUSE:
Mechanize::request() method sets the "Referer" header for the underlying
request object using this code:
$request->header( Referer => $self->{last_uri} ) if
$self->{last_uri};
However, the $self->{last_uri} happens to be a ref to the object of type
'URI::http',
This is then being passed to Headers.pm method _header(). There, the
$val variable
if checked to be either !ref($val), or ref($val)=='ARRAY', neither of
which is the case.
--------------------------
PROPOSED FIX:
--------------------------
Use this code instead:
$request->header( Referer => "$self->{last_uri}" ) if
$self->{last_uri};
Note that here the $self->{last_uri} is enclosed in quotation marks
which would
effectively stringify the value before passing it in.
