Version 1.2 reflection EXC_BAD_ACCESS

Following code worked fine in 1.1 and stops working at the reflection reflect(a) in 1.2

class AClass {
    var some : String = "Hans"
    var thing : Double
    init( t: Double ) {
        thing = t
    }
}

class BClass : AClass {

}

var a = BClass(t: 1.1)

var mirror = reflect(a) // FAILS
for var index=0; index<mirror.count; ++index {

}

Though reflect(a).valueType would work and in addition give more meaningfull output/information than before.

Which leads me to two questions:

1. 
   

   Does anybody know what changed with reflection? What could be wrong? Previously i could also iterate over the properties of the Object.

   
   


2. 
   

   Where can i inspect such changes? I don`t find anything about reflection in the offical documentation and there are no notes about reflection changes on the blog or anywhere else, can i browse the source somehow? (never tried)
