Ok, it definitely looks like Mono being a little naughty but it's a simple
fix.
The offending code is:
uniqueId = reader.GetInt32(reader.GetOrdinal("RealContentItemId"));
and the fix is:
uniqueId = reader.GetOrdinal("RealContentItemId");
It seems that GetOrdinal is returning an Int32 and we then try to convert to a
(wait for it) Int32. Mono should just ignore this code but it doesn't.
Actually, the programming team never should have written it like this, but
hey, Mono should handle this kind of stupidity.
