NSLog and " character

[Riccardo Mottola]

Hi,

I'm expanding a CVS parser in DataBasin. I'm trying to parse a quoted 
CSV file.

The code snippet is:

      NSLog(@"2 %@, remaining: %@", field, [[scanner string] 
substringFromIndex: [scanner scanLocation]]);
      [scanner scanString:qualifier intoString:&token];
      if (token != nil)
        {
          NSLog(@"token: %@");

now I expect token to be the qualifier ("). NSLog however dies. Why? I 
get the backtrace below and as you may see, if I print out the object in 
GDB, it is indeed the string I so expect. Why is NSLog spitting into my 
face? Did I find some obscure bug or am I missing the obvious in my code?

Thank you,

Riccardo
