Description flo 2007-07-03 17:49:28 UTC 
Version:           0.8.1 (using KDE 3.5.5, Gentoo)
Compiler:          Target: i686-pc-linux-gnu
OS:                Linux (i686) release 2.6.20-gentoo-r8

In the question and answer session is a bug which let KWordQuiz crash. If you press the "Hint" button as often as possible (until there isn't any more character to display and the searches word is complete) and then press "Check" or Return KWordQuiz isn't responsing anymore. When you then press the X in the top right corner of the window a warning from KWin comes and you can either choose to terminate KWordQuiz or to keep it running.
You can reproduce it as often as you want...

The described problem only arises when "Treat hint as error" is activatet in the Quiz settings.
Comment 2 Philip Rodrigues 2007-07-04 00:10:02 UTC 
When KWordQuiz freezes, try killing it with "kill -SEGV <pid-of-kwordquiz>". That might get you a backtrace. If so, please paste it here.

Unfortunately the backtrace isn't very useful because your kde is built without debugging symbols, but you can find instructions for producing more detailed backtraces here:
