Created attachment 59658 [details] Test for an interface
The bugs appears to come from the fact the QueryInterfaces fails.
The patch shows that this interface exist when using the jet DataSource. We may need to hold a reference to that data source object and Query it when a interface isn't directly supported in IDataInitialize.
After more investigation, this is incorrect.
