Résolution
In Winter '15 (API version 32.0), a number of additional sObjects are available including ListViewRecord, which had the following definition: 
 <complexType name="ListViewRecord">
     <sequence>
     <element name="columns"  type="tns:ListViewRecordColumn" maxOccurs="unbounded"/>
     </sequence>
</complexType>

 As a result .Net integrations fail due to the error shown in the details section due to a bug in .NET's XmlSerializer as described in the following link: A workaround involves replacing all occurrences of [][] with [], to then recompile the app.
