This is very perplexing. I see this error changing the visibility of a column after it has been added to the treeview. I think the error is coming from the accessibility code that wants to report the number of visible columns. The methods reported in the error have existed since November 2011. This may be a Gtk defect, or it is considered an error to change a column's visibility once the treeview has drawn.

I may write a test to reproduce this and send it upstream.

I have changes in place that disable the checkboxes instead of hiding the column. This is not ideal, but may be what we must accept if changing column visibility is wrong in Gtk.

I also see this error when I hide the viz window's Revision Number Column or Date Column.

I am setting this aside. I am not convinced that bzr-gtk is doing anything wrong. I wonder if this is a defect in the the Gtk accessibility libs. I have seen this error in other apps too.
