GtkCellRendererText "edited" signal not emitted when clicking out of cell

Note that the upstream bug has a simple fix for this, though I'd rather that Ubuntu Oneiric was just updated to the latest stable GTK+ release instead of applying an individual patch.
https://bugzilla.gnome.org/show_bug.cgi?id=653289#c12

Marking as Fix Released because this is fixed in Ubuntu Precise because that has a newer version of GTK+.

Trying to follow the procedure from here:
https://wiki.ubuntu.com/StableReleaseUpdates

[Impact]
This causes loss of data in applications that use GtkTreeViews to edit data. If the user is unlucky then he will not even notice. It's most obvious impact is in the GTK+ file chooser when creating a directory, and in Nautilus when renaming files. The new file names are lost unless the user explicitly types Enter. This was a regression compared to GTK+ 2.

[Development Fix]
Ubuntu Precise does not have this problem because it has a later version of GTK+ that includes the fix. GTK+ fixed this in a stable bug-fix release.

[Stable Fix]
This patch fixed it upstream:
https://bugzilla.gnome.org/show_bug.cgi?id=653289#c12

[Test Case]
In the Nautilus file manager, right-click a file and choose "Rename ...". Change the file name. Click on a different file. The new file name will be lost. It will only be retained if you press Enter instead of clicking away.

[Regression Potential]
This fix has been upstream for a long time now and no problems have been reported.

(Is there some Launchpad bug that keeps changing the Package from gtk+3.0 to none? Maybe an escape() or encodeURI() that should be an encodeURIComponent()?)

Subscribing sponsors, the fix to backport is http://git.gnome.org/browse/gtk+/commit/?h=gtk-3-2&id=126adb6ef3f99468eb9bf9c133c216173acc20bc

I uploaded that patch to oneiric-proposed, awaiting ubuntu-sru review now.

Hello Murray, or anyone else affected,

Accepted gtk+3.0 into oneiric-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

Could anyone please test the version in -proposed? Thank you!

Following the test case in comment #3, I'm able to verify that 3.2.0-0ubuntu6 does fix the issue.

I too can confirm that it fixes the Nautilus renaming problem.

This bug was fixed in the package gtk+3.0 - 3.2.0-0ubuntu6

  * Add git_push_error_traps_around_xiquerydevice_calls.patch:

    input devices mysteriously disappear. (LP: #882956)

gtk+3.0 (3.2.0-0ubuntu5) oneiric-proposed; urgency=low
