After receiving a response to this bug, I have updated libgail so that 
text-caret-moved signal is emitted when text is inserted into a GtkTreeView.

If the accessible object for a check box in a table exists the "state-change" 
signal is emitted on the accessible object. I have updated ferret so that 
notification of emission of "state-change" signal is received.

The "visible-data-changed" signal is emitted on the accessible object 
corresponding to the GtkTreeView. If there is a consensus that this behavior is 
incorrect I will remove that emission.
