DataContractJsonSerializer Serializes item, then cannot deserializ

Tech-Archive recommends: Speed Up your PC by fixing your registry

the JSON that is being emitted is being stored in a DB as an object state,
then fails to deserialize properly from that value. We've simplified it,
bypassing the database, encoding, etc and it still fails, however we are
serializing the exact same types in other areas of the application using the
same shared method and they all work just fine.

Here is the JSON that it is blowing up on:

"[{\"CLRTypeName\":\"DateTime\",\"Defaultvalue\":\"11\\\/22\\\/2008\",\"ParameterName\":\"StartDate\",\"ParameterType\":\"3\",\"ParameterValue\":\"\",\"Prompt\":\"Start
Date\",\"ValueList\":[]},{\"CLRTypeName\":\"DateTime\",\"Defaultvalue\":\"12\\\/22\\\/2008\",\"ParameterName\":\"EndDate\",\"ParameterType\":\"3\",\"ParameterValue\":\"\",\"Prompt\":\"End
Date\",\"ValueList\":[]},{\"CLRTypeName\":\"Int32\",\"Defaultvalue\":\"-1\",\"ParameterName\":\"LeaveReason\",\"ParameterType\":\"1\",\"ParameterValue\":\"-1\",\"Prompt\":\"Leave

condition\",\"18|ENLIST - Enlistment\",\"29|FMQE - Family Member Qualifying
Exigency\",\"23|SHCMIL - Family Military Member SHC\",\"3|FAMHEALTH - Family

Injury\"]},{\"CLRTypeName\":\"Int32\",\"Defaultvalue\":\"-1\",\"ParameterName\":\"WorkType\",\"ParameterType\":\"1\",\"ParameterValue\":\"-1\",\"Prompt\":\"WorkType\",\"ValueList\":[\"-1|-
ALL -\",\"1|Continuous Leave\",\"2|Intermittent Leave\",\"7|Medical

ALL -\",\"3|SPARTANBURG REGIONAL HEALTHCARE SYSTEM -

And then we tried a simple XmlObjectSerializer for the same type and
recieved the same error (here's the object Xml string that was generated and
failed):

Finally, here is the error and stack trace we're getting back form the
deserializer:

Any help would be greatly appreciated.
