This bug was fixed in the package ubuntu-ui-toolkit - 0.1.46+13.10.20130710-0ubuntu1

---------------
ubuntu-ui-toolkit (0.1.46+13.10.20130710-0ubuntu1) saucy; urgency=low

  [ Kaleo ]
  * Add a CrossFadeImage component which crossfades when its source is
    updated.
  * Standard animation durations adapted for new design: - SnapDuration
    goes from 125ms to 100ms - FastDuration goes from 250ms to 165ms -
    new BriskDuration is introduced at 333ms.
  * GIconProvider: avoid using QPixmap which is not re-entrant. Fixes
    crashes. (LP: #1197784)
  * Fine tuned UbuntuAnimation.StandardEasing to match design.
    Introduced new standard Ubuntu easing
    UbuntuAnimation.StandardEasingReverse.
  * Panel.animating: do not rely on comparing real values that sometimes
    have rounding errors. (LP: #1199550)

  [ Iain Lane ]
  * Add a CrossFadeImage component which crossfades when its source is
    updated.

  [ Loïc Molinari ]
  * [UbuntuShape] Moved content flagging before implicit sizing to
    prevent assertion.
