[orca-list] Strange message in the log

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

Hi all.
This is not related to orca but I am posting hear in the hope that 
someone can help identify the reason.

In the log of my arch box I found the following message:
Sep 16 14:31:39 jve gnome-session[555]: (thunderbird:1270): 
GLib-GObject-WARNING **: gsignal.c:3429: signal name `selection_changed' 
is invalid for instance `0x7f5cda872ed0' of type `MaiAtkType3'

It seems that the message appears everytime  I press down/up arrow in 
the list messages of thunderbird.

Questions:
Is this a problem?
Where to report?

Thanks.
Thanks.
