Bug Description

Current ubiquity crashes when running under pygobject 2.90. Easy local reproducer in a built ubiquity tree is:

$ GI_TYPELIB_PATH=src/webcam PYTHONPATH=. python -c 'from gi.repository import Gtk; import ubiquity.gtkwidgets; b=Gtk.Builder(); b.add_from_file("gui/gtk/stepPrepare.ui")'

I bisected this to http://git.gnome.org/browse/pygobject/commit/?id=7bc4122897, which explains why it works in the pygobject-2-28 branch (as this commit got reverted there to not break the pygtk ABI).

This might be a bug in GTK3's image builder or pygobject itself.

I reported this upstream with a small self-contained reproducer. I uploaded a workaround to ppa:ubuntu-desktop/ppa, so if we will update pygobject to 2.90 in oneiric (see bug 828751), I'll keep this applied until this gets fixed properly.

This bug was fixed in the package pygobject - 2.90.2-2

---------------
pygobject (2.90.2-2) experimental; urgency=low

  * Add revert-refcount-fix.patch: Revert
    http://git.gnome.org/browse/pygobject/commit/?id=7bc4122897 as a
    workaround for segfaults when creating custom widgets through the GObject
    constructor (such as through GtkBuilder). This works around
    https://bugzilla.gnome.org/show_bug.cgi?id=657403. This patch was reverted
    in the 2-28 branch as well, so reverting it here is no regression from
    2.28. (LP: #834168)

pygobject (2.90.2-1) experimental; urgency=low

  * New upstream bug fix release.
  * debian/copyright: Update to current licenses/copyrights, and convert to
    DEP-5.

pygobject (2.90.1-1) experimental; urgency=low

  * debian/control.in: Update Vcs-* for experimental branch.
  * New upstream release:
    - New rewritten invoker is twice as fast and easier to extend and debug
    - Complete break from static bindings so we may improve the core without
      breaking legacy APIs
    - Better type handling
    - Parallel installable with PyGObject 2.28 for legacy binding support
      (2.28 must be compiled with –disable-introspection)
    - Fixed object array handling
    - Added more overrides for PyGTK API emulation
    - Support for function calling using keyword arguments
    - GObject and GLib symbols can now have overrides
    - All static bit removed or made private
    - GVariants now work from callback returns
    - Note that this now enforces a consistent move to the GI bindings. I. e.
      you need to change all "import gobject" statements into "from
      gi.repository import GObject", same for glib.
   * Drop debian/patches/00git_*.patch, all upstream.
   * Drop 20_deprecated_spam.patch, obsolete.
   * debian/control.in: The static bindings (glib, gobject, pygtk, gtk, etc.)
     are deprecated and are now shipped in the separate packages
     python-gobject-2{,-dbg}. Add a dependency to these for the time being to
     not break backwards compatibility. Once all packages have been ported to
     use the GI bindings, this dependency and pygobject-2 will be dropped.
   * debian/control.in: Update package descriptions to point out that this is
     now GI only.
   * debian/control.in, debian/rules: Drop python-gobject-dev package. It's
     not relevant any more for this version, and now built from the
     pygobject-2 source package.
  * debian/rules: Bump shlibs.
  * Drop debian/python-gobject.examples: These are for the old static
    bindings. http://git.gnome.org/browse/pygobject/tree/demos is an actually
    useful and comprehensive example, but not shipped in the release tarballs.
  * debian/rules: Drop obsolete permission fixing, that only applied to the
    examples.
