Hi, Luke. The speed in gconf-editor is a big problem, but not technically a bug. However, if you tab over to the Name/Value table, you can hear the namee, but the value always says "blank", regardless of the value type. The values themselves are not accessible. This is because the cell renderer is using the get_size callback to set the values on the cell just prior to rendering. The gail module reads data from the treeview model for Orca, and if it's missing, all it can say is "blank". I think we need to instead cache the data when the cell renderers are called.
This might have two benefits. First, many applications, like gconf-editor, would suddenly become acccessible. This is perhaps the most common reason GTK+ apps are not accessible. Second, we might avoid the huge delays that occur today when we tab to a huge treeview. By only updating the data as it's rendered, we should see no noticeable slow down. However, that slow down may be due to some unrelated code. We'd have to dive in and see.
