accerciser crashed with AttributeError in __main__: 'module' object has no attribute 'PARAM_APP_DATADIR'

according to upstream (debian):

"The problem here is due to the fact we have changed python helper
(pysupport to dh_python2) and that all the packages that share the same
namespace MUST use the same.

I should have added tighter Breaks/Dependencies but there are quite
some packages involved and that was not that trivial."

Do I need to do particular steps to get the crash? On current oneiric I did "sudo apt-get install accerciser", run "accerciser", and get the main window. The main window displays an exception

Traceback (most recent call last):
  File "/usr/lib/pymodules/python2.7/accerciser/plugin/base_plugin.py", line 156, in __call__
    return self.func(*args, **kwargs)
  File "/usr/share/accerciser/plugins/interface_view.py", line 91, in init
    section = _InterfaceSection(ui_xml, self.node, iface_name)
  File "/usr/share/accerciser/plugins/interface_view.py", line 167, in __init__
    self._setExpanderChildrenSensitive(False)
  File "/usr/share/accerciser/plugins/interface_view.py", line 226, in _setExpanderChildrenSensitive
    label = expander.get_label_widget()
AttributeError: 'NoneType' object has no attribute 'get_label_widget'

but this seems unrelated? (the window doesn't crash)

Ah, this is due to some leftover files:

I committed a fix to the Debian svn, and uploaded a test package to https://launchpad.net/~pitti/+archive/ppa -- would you be able to test this? It should clean up the cruft.

I confirm that the package from the PPA fixes this issue with accerciser.

This bug was fixed in the package gnome-python - 2.28.1-3

---------------
gnome-python (2.28.1-3) unstable; urgency=low

  [ Josselin Mouette ]
  * Drop incorrect ${python:Provides}.

  [ Martin Pitt ]
  * debian/control.in: Add Conficts/Replaces: python-gnomecanvas. This only
    existed in Ubuntu (which now is getting rid of this delta), and is a
    no-op for Debian.
  * debian/watch: Fix syntax to actually catch latest version. Also move to
    *.bz2, upstream does not release .gz tarballs any more.
  * debian/python-gnome2.postinst: Remove old __init__.py{,c} cruft from
    pysupport, which causes bad imports after upgrades. (LP: #790613)
