[Launchpad Bug Tracker <914033@xxxxxxxxxxxxxxxxxx>]

This bug was fixed in the package qt4-x11 - 4:4.7.4-0ubuntu8.1

---------------
qt4-x11 (4:4.7.4-0ubuntu8.1) oneiric-proposed; urgency=low

  * Fixes LP: #914033, threading crashes in Libreoffice using KDE theme
  * Add kubuntu_30_xlib_calls_threadsafe.diff
   - let Qt call XInitThreads(), so that it knows it's been called
     Otherwise QPixmap complains when used outside of the main Qt
     thread and resets itself to null pixmap, eventually leading to
     crashes.

  Upstream reports that Libreoffice and Qt need a patch each to work together with 
  Libreoffice 3.4 and Qt 4.7, this is because of assumptions about threading.
