[Bug 911834] Re: software-properties-gtk crashed with AttributeError in on_treeview_sources_cursor_changed(): 'NoneType' object has no attribute 'get_selected'

[Martin Pitt]

Do you have some steps how to reproduce this? Can you still reproduce it
with today's python-gi update?

Thanks!

pygobject (3.0.3-2) unstable; urgency=medium

  * Urgency medium as the previous release with the regression already made it
    into testing and is causing quite a few unexpected breakages.
  * Add 01_revert_tree_model_unicode_conversion.patch: Revert "Convert all
    strings to utf-8 encoding when retrieving from TreeModel" change from
    previous release. This changes existing behaviour (model values being str
    instead of unicode) and also makes tree model behaviour incompatible to
    the rest of Gtk behaviour (which always returns UTF-8 encoded str objects,
    not unicode). The original bug description was a bug in the test case
    code, you cannot mix str and unicode objects in interpolation.
    (LP: #905602)
