WP plugin: content header issue with version 1.5

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Updated the pubsubhubbub plugin to the latest version 1.5
2. Posted information on my website
3.

What is the expected output? What do you see instead?
Expected outcome was to be taken back to the list of posts instead I am taken 
to a google page with the following 

Warning: Cannot modify header information - headers already sent by (output 
started at 
/home/hadfield/public_html/wp-content/plugins/pubsubhubbub/publisher.php:73) in 
/home/hadfield/public_html/wp-includes/pluggable.php on line 890

What version of the product are you using? On what operating system?
Version 1.5 Windows Vista OS Wordpress for the site. 

Please provide any additional information below.
I updated 4 other plugins at the same time, all work fine, I have deactivated 
the hubbub and the posts work with no  error, but I want the hubbub to be 
working also.

HI

I had the same issue and now deactivated pubhub again since I couldn't find any 
solution. Here's something I came across but no idea if this applies to us too 
because I am a total dummy with that kind of stuff.

This one guy wrote that this is the problem:

<?php
header("Location: $strReturnhtml");
?>

and that this should be the solution

Output-Buffering:
Before
session_start();
you would have to enter
ob_start();
and at the end of the script enter
ob_end_flush();

It did work for this one guy who had the same error message.
