[pygtk] Replacing text with paste

I manage my own undo buffer of changes made to a gtk.TextView. This
necessarily means that the undo controller is connected to the relevant
TextBuffer's "delete-range" and "insert-text" signals. Changes made
during these signals are stored on the undo stack.
Then I ran into some weird behavior: when I select any region of the
text in the text buffer and then paste something in that was previously
copied to the clipboard, an "insert-text" and then a "delete-range"
signal is emitted. This means that, when undoing, the "delete-range" is
undone first and this leaves both the originally selected text as well
as the text it was replaced with in the TextView, until undo is called
again, undoing the "insert-text" changes.
Is there a signal I can connect to to catch this special case, or does
anyone have another idea of how to combine these two into a single undo
Thanks in advance,
