Getting field by name using reflect panics when checking IsZero

I have a piece of reflection code that attempts to get the field on a struct by name and then checks if the field exists:

type test struct {
   A bool
   B bool
}

t := new(test)
metaValue := reflect.ValueOf(t)
field := metaValue.FieldByName(name)
if field.IsZero() {
    glog.Errorf("Field %s was not on the struct", inner)
}

According to the documentation on FieldByName, this function should return a zero value if no field was found. However, the very next line panics with the error:

panic: reflect: call of reflect.Value.IsZero on zero Value

goroutine 268 [running]:
reflect.Value.IsZero({0x0, 0x0, 0x112a974})
        reflect/value.go:1475 +0x27f

According to this GitHub issue, this should only happen if the Value contains nil (i.e. no type) and IsValid should be used instead. Why is this happening?
