Integration Testing with SES Enabled Fails

I just started trying out some testing and for some reason when I have SES enabled, the tests will not work. As soon as I disable the interceptor, everything works fine.

Any ideas?

Here is the error:

Complex object types cannot be converted to simple values.

The expression has requested a variable or an intermediate expression result as a simple value. However, the result cannot be converted to a simple value. Simple values are strings, numbers, boolean values, and date/time values. Queries, arrays, and COM objects are examples of complex values. 

 The most likely cause of the error is that you tried to use a complex value as a simple one. For example, you tried to use a query variable in a cfif tag.
