Statechart transitions not shown in diagram.

Hi! I'm new to ArgoUML and when I create a statechart diagram, I can't 
see the transitions. I can see in the properties window the transition, 
and the the source and target is ok, but I can't see the arrow in the 
diagram. What I've done is this:
1) Open ArgoUML
2) Create a new class named Test
3) Create -> New Statechart Diagram
4) Create a new state
5) Click on the left arrow on the new state to create a new one and a 
transition

Now in the diagram I see the 2 states, but no transition arrow, but the 
transition is in the model. In the State-centric view, it shows the new 
(anon Transition) hanging from the created SimpleStates.

I'm using it right? Is this a bug?

I'm using ArgoUML debian unstable package (0.19.6-2.1) with Sun Java 6 
JRE debian package (6-02-1).


Here is the standard output of the running ArgoUML:
