software-properties-gtk crashed with AttributeError in on_treeview_sources_cursor_changed(): 'NoneType' object has no attribute 'get_selected'

Status changed to 'Confirmed' because the bug affects multiple users.

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.

i got this with upto date packages today. I opened software sources from the system settings and then closed it without changing any options.

I was able recreate this bug report until I installed python-gobject version 3.0.3-2. After installing that new version software-properties no longer crashes.

Python-gobject 3.0.3-2 here and I'm able to reproduce this. I haven't got an exact recipe for it, but enough wiggling around in software sources (with the mirror and such) seems to bring it on. I *think* it happens only when I finally close the window and not before. I'll keep looking for the exact steps, but I'm pretty confident this is still unfixed, as apport always points me to this report.

I am using i686 and facing the same problem

python-gobject 3.1.1-ubuntu1, and for the rest its the same as what Jani describes. If I wiggle around in software sources and close the window I get this error.

This happens when closing software-properties-gtk with the window close X instead of the close button.

This bug was fixed in the package software-properties - 0.82.5

---------------
software-properties (0.82.5) precise; urgency=low

  * softwareproperties/gtk/SoftwarePropertiesGtk.py: Drop duplicate definition
    of on_treeview_sources_cursor_changed().
  * softwareproperties/gtk/SoftwarePropertiesGtk.py: Fix crash when closing
    the application with the window title bar button. (LP: #911834)
  * add-apt-repository: Intercept ValueError in addition to URLError, as this
    is the error thrown when trying to decode invalid JSON (which happens on
    404 pages etc.). (LP: #861258)
  * softwareproperties/SoftwareProperties.py, _find_source_from_string():
    Reload the sources list before searching, as it might have changed while
    the D-BUS backend was running. (LP: #854818, #820150)
  * softwareproperties/gtk/SoftwarePropertiesGtk.py: Add missing argument to
    menu popup() call. (LP: #815236)
