The badness is subtle, but is buried there in the output.
In the internal dictionary, the first listed key is of type CFNumber.
To be a valid property list, a dictionaries keys must be CFStrings.
The other types of plist objects are not valid keys in a plist
dictionary.

This method works in all of the places it is used, except for a
particular NSDictionary. The output of the above NSLogs for the
offending NSDictionary are as follows:

As you can see, the NSDictionary is made up entirely of legitimate
object types for plists... I have tried a number of things, and I
have all but given up. Thanks to those of you who put in an effort to
understand the problem (sorry for sending all this crunky output).
