NSXMLParser Leaking

I have the following code that leaks. Instruments says that it is the rssParser object that is leaking. I "refresh" the XML feed and it runs the block and it leaks....

file.h

@interface TestAppDelegate : NSObject <UIApplicationDelegate> {

    NSXMLParser *rssParser;

}

file.m

NSData *data = [ NSURLConnection sendSynchronousRequest:request returningResponse: nil error: nil ];
    rssParser = [[NSXMLParser alloc] initWithData:data];
    [rssParser setDelegate:self];
    [rssParser setShouldProcessNamespaces:NO];
    [rssParser setShouldReportNamespacePrefixes:NO];
    [rssParser setShouldResolveExternalEntities:NO];
    [rssParser parse];
    [rssParser release];
