NSMutableDictionary is adding quotes to keys and values - why?

Question

I'm trying to add some additional key/value pairs to an NSMutableDictionary, using:

Tag *tag1 = [results1 objectAtIndex:0];
[resultsDict setObject:[tag1 retrieveTextUpToDepth:1] forKey:@"image_url"];

Tag *tag2 = [results2 objectAtIndex:0]; 
[resultsDict setValue:[tag2 retrieveTextUpToDepth:1] forKey:@"majority"];

This adds the k/v pairs with no problem, except when I come to retrieve them, some of the values have been wrapped with double quotes:

po extendedDataDictionary:

    "image_url" = "/images/mpsL/11727.jpeg";
    majority = 3460;

Both keys and values are NSStrings, with no quotes - so I'm stumped as to where they're appearing from.

Is there any way of preventing this?

Or am I going to have to live with it and try to strip off the quotes once I've retrieved the value?

Thanks...

The quotes aren't really part of the content; the -description method (called by po, IIRC) simply wraps things in quotes for display that have non-alphanumeric characters in them.
