[orca-list] trace back message when using eclipse

[José Vilmar Estácio de Souza <vilmar informal com br>]

Hi all.
I found the following  and  I suspect it has something to do with the 
bug 618334.
For while I do not know how to create a test case but I can reproduce 
all the time.

Traceback (most recent call last):
