hgview #8399 mercurial 1.2 compatibility [validation pending]

Has anyone else tried hgview (http://www.logilab.org/project/hgview) under Mercurial 1.2? It's not showing log messages for me. And it prints this stack trace many many times:

Traceback (most recent call last):
 File "/home/scratch/src/hgview/build/lib/hgview/gtk/graphrenderer.py",line 203, in on_render
   node_branches = self.app.get_node_branches()
 File "/home/scratch/src/hgview/build/lib/hgview/gtk/hgview_gtk.py", line 160, in get_node_branches
   node_info = self.repo.read_node(node)
 File "/home/scratch/src/hgview/build/lib/hgview/hgrepo.py", line 181, in read_node
   if node in nodeinfo:
TypeError: list objects are unhashable

If I downgrade back to 1.1.2, both problems go away.
