Objc: NSRangeException when PUT/POST

[GoogleCodeExporter]

When I try to execute a code like that:

{{{
id<OASignatureProviding> signatureProvider = [[OAPlaintextSignatureProvider 
alloc] init];
            OAMutableURLRequest *oauthRequest = [[OAMutableURLRequest alloc] initWithURL:[NSURL URLWithString:self.auxApiURL] consumer:self.auxOAuthConsumer token:self.auxOAuthToken realm:nil signatureProvider:signatureProvider];
            [oauthRequest setHTTPMethod:@"PUT"];
            [oauthRequest setHTTPBody:deleteJSON];

            [oauthRequest prepare];
}}}

I get a NSRangeException:
{{{

}}}

I see a little patch in the Ubuntu One source code that I think that solves the 
problem:
