I found a similar issue. I found and reported the problem to the Qt people.
A fix for this bug has been committed upstream:
https://qt.gitorious.org/qt/qtbase/commit/d40b66a8ef98777c69ac293dac9a332f88832c23
I verified that it indeed fixes the bug. It is easy to reproduce: run
/usr/local/lib/qt5/examples/assistant/simpletextviewer/simpletextviewer ,
then click Help -> About. In the current situation, the application
will crash when you click "OK". With the patch applied, it doesn't
crash.
Best regards,
Caspar Schutijser
