Dapper 1.13 introduces bug to dynamic types

[GoogleCodeExporter]

I have code that looks like the following:

var data = connection.Query(sql);
foreach (dynamic row in data)
{
    row.NewDynamicProperty = 5;
}

Since the type returned is dynamic, I expect to be able to add my own property 
on the fly. This worked in Dapper 1.12, but not in the 1.13 release. The 
exception thrown is:

Exception type: ArgumentException 
Exception message: Incorrect number of arguments supplied for call to method 
'System.Object SetValue(System.String, System.Object, Boolean)'

Yep, got it too. DapperRow now "typed" in DapperTable, so no new members 
possible in this "dynamic".

This binding only fails on primitive types. Consider wrapping to object as work 
around.

I plan on looking into this issue this week. No breaking change was intended.

I'm also getting breakage around this.
A fix will be great.
