Comment 1 Christoph Feck 2010-01-05 15:33:43 UTC 
Since this looks like a Qt bug, I reported it as http://bugreports.qt.nokia.com/browse/QTBUG-7139
Comment 2 Christoph Feck 2010-01-06 23:35:35 UTC 
If the bug is reproducable on your system anytime, could you please provide the following information:
- the used locale ("set | grep LANG")
- the DPI setting ("xdpyinfo | grep inch")
- the used font and font size ("kcmshell4 fonts", General font)

If you use a non-standard font, please provide the location where you downloaded it.

This information would be helpful to reproduce the crash and find a fix. Thanks!
