I have implemented

- (NSString *)descriptionWithLocale:(id)locale
{
   return [NSString stringWithFormat:@"<data of length %d>", [self length]];
}

no in my category, but this method isn't used either by NSLog(@"dic %@", dic)!? 
:-(

I checked core/base/Source/NSData.m but it has no implementation for 
descriptionWithLocale: either!?

Thanks,

 Andreas
