Comment 1 for bug 494140

gtk.link_button_set_uri_hook is referenced in revisionview.py
gtk.Action.set_tool_item_type is referenced in viz/branchwin.py

These are PyGtk 2.10 innovations. debian-etch supplies PyGtk 2.8.6-8

Both uses appear to be 'cosmetic' - they do not seem to set up or manipulate objects that the code later relies upon.

As a workaround - to prove that the remainder of the code runs successfully - simply commenting out these references seems to be effective. But I don't have enough knowledge of python, gtk or the bzr-gtk codebase to know whether there are unacceptable consequences to this.

'Proof of concept' branch proposed for merge to encourage discussion.
