creating a NSURLRequest causing iPhone app to crash

My iPhone app crashes when I try to create an NSURLRequest object. However, I know the url object I'm using is correct. Code and console log are both below. Any advice?

NSURL *url = selectedObject.url;
NSLog(url);
NSURLRequest *tempURL = [NSURLRequest requestWithURL: url];
NSLog(@"got here");

And console log:

2010-11-07 20:41:46.465 DePauw[17643:207] CALayer position contains NaN: [605712 nan]
2010-11-07 20:41:47.988 DePauw[17643:207] CALayer position contains NaN: [59100 nan]
2010-11-07 20:41:49.389 DePauw[17643:207] CALayer position contains NaN: [4405 nan]

2010-11-07 20:41:54.243 DePauw[17643:207] http://www.depauw.edu/m/

As you can see, it prints the NSLog(url) (www.depauw.edu/m/) so I know my url is what I intend it to be. However, it doesn't print the NSLog(@"got here). Even t开发者_运维技巧hough the program crashes at the NSURLRequest line, the console doesn't generate any crash report or any error, which is what is confusing me. Any thoughts?
