[NSUserDefaults setObject:forKey:]: Attempt to insert non-property valu

Question

Hi all
I have been writting classes at work in Xcode 4.? SL 10.6.8 and every thing has been working fine. When I bring a copy home to work on under Lion in Xcode 4.3.2 I get issues (Lots of them)
While I have solved or worked around most I am unsure why I am getting an error with my NSUserDefaults.
I have a method that I run in a singleton
+ (void)setSaveLocation : (NSString *) saveLocation
    NSMutableDictionary * ccLogManagerDictionaryFromUserDefaults = [[NSMutableDictionary alloc] initWithDictionary:[[NSUserDefaults standardUserDefaults] valueForKey:@"CCLogManager"]];
    [ccLogManagerDictionaryFromUserDefaults setObject:saveLocation forKey:@"Save Location"];
    [[NSUserDefaults standardUserDefaults] setObject:ccLogManagerDictionaryFromUserDefaults forKey:@"CCLogManager"];
    [ccLogManagerDictionaryFromUserDefaults release];
    // Post a notification to inform other classes that the savelocation has changed
    NSNotificationCenter *notification = [NSNotificationCenter defaultCenter];
    [notification postNotificationName:@"CCLogManagerNotificationSaveLocation" object:self];
This worked fine before. The only change I have made is to the method in a different class that send the information :
- (IBAction)changeSaveLocation: (id)sender
    NSOpenPanel* openDlg = [NSOpenPanel openPanel];
    [openDlg setCanChooseFiles:NO];
    [openDlg setCanChooseDirectories:YES];
    if ( [openDlg runModal] == NSOKButton )
        NSArray* files = [openDlg URLs];
        int i;
        for( i = 0; i < [files count]; i++ )
            NSString* fileName = [files objectAtIndex:i];
            [CCLogManager setSaveLocation:fileName];
I had to change two lines due to depreciation:
    if ( [openDlg runModalForDirectory:nil file:nil] == NSOKButton )
and
        NSArray* files = [openDlg filenames];
What I dont understand is that I am still passing a NSString as required. And if in the first method I simpy insert a @"" string like so
    [ccLogManagerDictionaryFromUserDefaults setObject:
@"file://localhost/Volumes/MacPro%20RAID/Home%20Folder/Downloads/8-tileable-meta l-textures/"  forKey:@"Save Location"];
Then it works
Any assistance would be most appreciated.
Cheers

Oh and the error is:
2012-06-14 22:41:31.843 ProControl[3630:403] *** -[NSUserDefaults setObject:forKey:]: Attempt to insert non-property value '{
    "Logging Enabled" = 1;
    "Save Location" = "file://localhost/Volumes/MacPro%20RAID/Home%20Folder/Downloads/8-tileable-meta l-textures/";
}' of class '__NSCFDictionary'.  Note that dictionaries and arrays in property lists must also contain only property values.
And it don't save to the User Defaults.

Hi etresoft, thanks for the reply.
Do you mean the number 1 pertaining to "Loggining Enabled" = 1?
If so this should be a   [NSNumber numberWithBool: YES] which is already in the userdefauts.plist. before copying the original dictionary.
The method save should be copying a dictionary from the .plist and only changing the dictionary entry for "Save Location" which is a NSString. It shouldn't be doing anything to the "Logging Enabled" entry which as I say should already be a NSNumber numberWithBool . Plus seeing as you can change the line
[ccLogManagerDictionaryFromUserDefaults setObject:saveLocation forKey:@"Save Location"];
to
[ccLogManagerDictionaryFromUserDefaults setObject:
@"file://localhost/Volumes/MacPro%20RAID/Home%20Folder/Downloads/8-tileable-meta l-textures/"  forKey:@"Save Location"];
and still not touch the "Loggining Enabled" = 1 I don't that the 1 is an issue.
Sorry if I'm being dense.
