Replying here as a reguestet by ign_christian in Bug 67011.

I can reproduce this on KDE 4.10.4 (I have mixed my KDE version with my
QT version above - sorry), also qtcore has since been upgraded to
4.8.4-r5).

Also, I'm sorry about the duplicate in bug (In reply to comment #25).
Howeveer, I'm not sure it should be marked as duplicate since 1) The bug
67011 happens on every spreadsheet, not just in certain circumstances 2)
It's not a crash (per se) but a total hang (inresponsiveness) of the UI
input (keyboard + mouse), and 3) There's no mention of KDE specificity
in this bug report and 4) This bug is for a very old version of
libreoffice compared to the version in bug 67011 (3.4.2 release vs.
4.1.0.2).

However, if you still feel it is a duplicate, it's OK of course. Maybe
reopen? Or, I could try to upgrade to KDE 4.10.5 (it's a long compile
and will take a while)?

Bug description:
  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.
