Please please please someone put me out of my misery! There must be something (extremely!) simple I am forgetting/doing wrong as I have tried this on several setups and I get the same result. Here is my HTML: 
<!DOCTYPE HTML><html><body>

Or upload a new file<br><br>
<form id = 'email-upload-form' name='email-upload-form' action='/cgi-b
+in/testform/upload.pl' method='POST'>
<input type = 'file' name='emailupload' enctype="multipart/form-data"/
+><button name='submit-button' id='upload-button' type='submit'>upload
+</button>
</form>

</body>
</html>

and my perl script to pick up the file: 
#!/usr/bin/perl

use strict;
use CGI;
use CGI::Carp qw(fatalsToBrowser);
my $query = new CGI();

print "Content-type: text/html\n\n";

my @params = $query->param;

print "params are @params<br>\n";

my $fh = $query->upload('emailupload');
print "fh contains $fh and is a ".ref(\$fh)."<br>\n";
print "fh is not defined!" if(!defined($fh));

print "$_\n" while(<$fh>);

The output of which, when I try to upload a dummy text file is 
params are emailupload submit-button
fh contains and is a SCALAR
fh is not defined!

In fact it does exactly the same thing if I hit 'upload' without first selecting a file.

BTW I read that doing operations on $fh other than file handle operations results in it losing its 'magic' and becoming a scalar - however even if I have 

#!/usr/bin/perl

use strict;
use CGI;
use CGI::Carp qw(fatalsToBrowser);
my $query = new CGI();

print "Content-type: text/html\n\n";

my $fh = $query->upload('emailupload');

print "$_\n" while(<$fh>);

I still get no output... I know I'm going to kick myself when I finally find out but.. can anyone identify what excruciating silly thing I am (not) doing?
