updated gtk+2.0 package has problems referring to the name of widgets loaded from a builder UI file

[Mario Limonciello]

The upgrade today has caused ubiquity to stop launching because it refers to widgets at the top level by calling setattr on them.

I've created a simple test case that i'm attaching. You can see it successfully running with the old gtk+2.0, and then failing with the new one here:

test@test-laptop:~$ python test.py
test@test-laptop:~$ sudo apt-get install libgtk2.0-0 libgtk2.0-bin libgtk2.0-common

  * Widget names are no longer stored in the widget's internal name, but
    rather in the object data. Sync this information back to the widget's
    internal name. (LP: #503710)

Marking the gtk task invalid. It appears to be a fundamental change in the code that any applications that run into this issue will just have to adjust for.

This bug was fixed in the package ubiquity - 2.1.7

  * Mythbuntu: Reconfigure mythbuntu-default-settings to ensure that the
    DefaultSession is set.
  * Only run hal-lock if hald is actually running due to changes in
    hal 0.5.14-0ubuntu2.
  * Widget names are no longer stored in the widget's internal name, but
    rather in the object data. Sync this information back to the widget's
    internal name. (LP: #503710)
  * Automatic update of included source packages: grub-installer
    1.49ubuntu1.

  * When setting the no persistence flag (-n), don't offer changing
    persistence in the UI. There's generally a good reason it's being
    disabled in the first place.
  * When a source image is provided in the startup flags, don't offer
    to select different images in the UI.
  * Widget names are no longer stored in the widget's internal name, but
    rather in the object data. Sync this information back to the widget's
    internal name. (LP: #503710)

  [ Evan Dandrea ]
  * Hack around GTK's lack of good label wrapping (again).
  * Point to correct location for the log file in the man page.
