Bug Description

The a11y_qt_and_qml_backport.diff patch as shipped in Oneiric does not initialize QDeclarativeItemPrivate::isAccessible meaning that when you try to valgrind a QML based application like unity-2d you get lots of
   Conditional jump or move depends on uninitialised value(s)
when the code uses the isAccessible variable.

Latest kubuntu_97_a11y_qt_and_qml_backport.diff already initializes QDeclarativeItemPrivate::isAccessible. It has been fixed by Fathi Boudra in http://bazaar.launchpad.net/~kubuntu-packagers/kubuntu-packaging/qt/revision/275 . This change has been uploaded to Precise in qt4-x11, 4:4.8.0-1ubuntu1.

Assuming we don't want to SRU this for Oneiric, I am closing the bug.
