RaptureXML weird behaviour

I am getting an error (well it doesn't shows, just crashes out of app, no info on console) that seems to happen whenever i call the method Iterate from RXML's rootXML:

-(void)valueSearch {
    //FIRST CONNECTION
    NSString *serverAddress = @"http://www.commix.com.br/clientes/grupoglobo/apple/valor.xml";
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:serverAddress] 
                                                       cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData
                                                   timeoutInterval:10];
NSError *requestError;
    NSURLResponse *urlResponse = nil;

    response = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&requestError];

    //SECOND CONNECTION - Just an encapsulated form of the first, since i use it in other parts
    // of the code
    response = [self requestWithParameters:@"valor.xml"];

    //i just uncommented both. but actually only one (connection) runs.

    //Creation of the rooXML so i can grab the info i need
    RXMLElement *rootXML = [RXMLElement elementFromXMLData:response];
    //This array is where i'll keep the info from the files.
    //it`s deallocated at the end in dealloc
    searchResult = [[NSMutableArray alloc] init];

    //This is the culprit. Atleast it seems so, since putting NSLog before and after
    //revealed so.
    [rootXML iterate:@"valor" usingBlock: ^(RXMLElement *valor) {
        NSLog(@"valor: %@", [valor child:@"nome"].text);
        [searchResult addObject:[valor child:@"nome"].text];
    }];
}

The thing is, when i comment the requestWithParametersand use the normal non-encapsulated style (//FIRST CONNECTION) i don't get errors. But if i use the second, when the program reaches [rootXML iterate: [...]]it crashes there without warning.

using RaptureXML: https://github.com/ZaBlanc/RaptureXML

It also happens in another part of the code:

-(void)vehicleSearch {

    NSString *path = [[NSBundle mainBundle] pathForResource:@"idArray" ofType:@"plist"];
    NSMutableArray *idArray = [[NSMutableArray alloc] initWithContentsOfFile:path];

    NSMutableString *serverAddress = (@"http://www.commix.com.br/clientes/grupoglobo/apple/modelo.php?marc=%@",[idArray objectAtIndex:0]);
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:serverAddress] 
                                                       cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData
                                                   timeoutInterval:10];

NSError *requestError;
    NSURLResponse *urlResponse = nil;
    response = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&requestError];

    RXMLElement *rootXML = [RXMLElement elementFromXMLData:response];
    searchResult = [[NSMutableArray alloc] init];

    [rootXML iterate:@"modelo" usingBlock: ^(RXMLElement *modelo) {
        NSLog(@"modelo: %@", [modelo child:@"nome"].text);
        [searchResult addObject:[modelo child:@"nome"].text];
    }];

    [idArray release];
}

Happens at the same line [rootXML iterate:].

Sorry for leaks and stuff, i'm inexperienced (thats why i'm here), Thanks!

EDIT: ACTUALLY the culprit is the line 

NSMutableString *serverAddress = (@"http://www.commix.com.br/clientes/grupoglobo/apple/modelo.php?marc=%@",[idArray objectAtIndex:0]);

if i pass the parameter directly, without variables, it works:

NSMutableString *serverAddress = (@"http://www.commix.com.br/clientes/grupoglobo/apple/modelo.php?marc=4");

it shows correctly.

Are you sure that ,[idArray objectAtIndex:0] is an NSString? Try to use

[NSString stringWithFormat:@"http://www.commix.com.br/clientes/grupoglobo/apple/modelo.php?marc=%@",[idArray objectAtIndex:0]];`

Or even

[NSString stringWithFormat:@"http://www.commix.com.br/clientes/grupoglobo/apple/modelo.php?marc=%@",[[idArray objectAtIndex:0]stringValue]];

response = [self requestWithParameters:@"valor.xml"];

if response is a property use self.response otherwise you will have memory leak issues.
