I'm using QMetaObjectBuilder and already calling setEnumOrFlag, so that 
doesn't seem to solve the problem.

An alternative that would work for me would be to bypass the new test if 
the meta-type was invalid (ie. the enum wasn't registered) but I don't 
know if that would nullify the purpose of the new test.
