This might be very minor problem,

But when I launch ironruby with rbd,

And at the very beginning hit enter with no input, anything I do results  
in:

unknown: Object reference not set to an instance of an object.  
(System::NullReferenceException)

I cannot even exit.

However, if you put in input the very first line, and try to give blank  
input after that works fine.

Is this an issue?

Thanks!

Tim

Can you try rbd -X:ExceptionDetail and send full output?
