Actually, this happened when you *thought* you were dragging a class. 
Actually, the drag occurs with the selected class, *not* the one you start 
the drag on (this is A BUG).

Browser>>dragPassengerFor:inMorph: returns self selectedClass, which can be 
nil.

This possibly also has to do with the commented-out code in 
PluggableListMorph>>startDrag:onItem: where the selected morph would be set 
to the morph being dragged if they weren't the same.

Uncommenting this commented code fixes your problem, but I don't know why it 
was commented. I'd be reluctant to suggest this as a fix without knowing more.

Anyone know?

Andreas?
