Description:
------------
Apache segfaults when you don't specify the first 3 parameters for fetch()

Reproduce code:
---------------
$oauth = new OAuth(TWITTER_CONSUMER_KEY, TWITTER_CONSUMER_SECRET);
$oauth->setToken('valid-key', 'valid-secret');
$oauth->fetch('https://api.twitter.com/1/account/verify_credentials.json');
$response = json_decode($oauth->getLastResponse());
var_dump($response);

The above code produces the issue described below. However, if the fetch line is changed to:

$oauth->fetch('https://api.twitter.com/1/account/verify_credentials.json', array(), OAUTH_HTTP_METHOD_GET);

The expected result is produced.


Expected result:
----------------
I expect to see a page with the contents of the $response variable

Actual result:
--------------
Apache segfaults and my browser prompts me to download a blank page with the same name as I'm viewing.

Is this oauth-1.2 or trunk?

 [2011-07-19 01:28 UTC] neenach2002 at gmail dot com 
I am using 1.2
 [2011-07-19 19:55 UTC] jawed@php.net 
This bug has been fixed in SVN.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on pecl.php.net.

In case this was a pecl.php.net website problem, the change will show
up on the website in short time.
 
Thank you for the report, and for helping us make PECL better.

Please lmk if this works for you.
