UITableView with NSURLRequest crashing my application

Question

I'm using a NSURLRequest to grab a comma-delimited list from my
webserver, split that into an array, then use that array to populate
my table. I have no errors when I create my own array using:
topScores = [[NSArray arrayWithObjects:@"23", @"20", @"5", nil] retain];
But when I use:
NSURLRequest *urlRequest;
urlRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.mysite.com/t.txt"]];
NSURLResponse *resp = nil;
NSError *error = nil;
NSData *result = [NSURLConnection sendSynchronousRequest:urlRequest
returningResponse:&resp error:&error];
NSString *blork = [[NSString alloc] initWithData: result encoding:
NSASCIIStringEncoding];
NSMutableArray *topScores2 = [NSMutableArray arrayWithCapacity:10];
topScores = [blork componentsSeparatedByString:@","];
My application crashes when I click on my UITableView.
The specific crash is:

I know the array I get from my NSURLRequest is valid because I can
access the elements manually by using [topScores objectAtIndex:4] , and
it access the right element.
I'm not sure what I'm doing wrong, but if anyone has any idea, I would
greatly appreciate it!
Thanks,
Pat

Hey thanks for the response! I had a little typo when formatting for this post. topScores2 can actually be omitted. I was trying different debugging things and forgot to take it out.
topScores is declared in the .h file and is an NSMutableArray. So the code is really:
NSURLRequest *urlRequest;
urlRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.mysite.com/t.txt"]];
NSURLResponse *resp = nil;
NSError *error = nil;
NSData *result = [NSURLConnection sendSynchronousRequest:urlRequest
returningResponse:&resp error:&error];
NSString *blork = [[NSString alloc] initWithData: result encoding:
NSASCIIStringEncoding];
topScores = [blork componentsSeparatedByString:@","];
