NSDictionary+MyCategory = crash?

Hi,
I have a static library in which I declare a category but when I use the declared method, the app simply crashes.


The catheroy method is dummy:

- (NSString *)formattedStringForKey:(NSString *)jsonXPath {
    NSLog(@"formattedStringForKey");
    return @"Test";
}

I set the -ObjC and  -all_load flags in the linker flags of the main app.

When I run the app in XCode, the entire XCode crashes ...

Any ideas what is going on?
