Comment 1 Vincent Danen 2010-06-12 00:33:01 UTC 
Based on the code, this looks applicable to webkitgtk (1.2.0, svn r56916) and qt (4.6.2, svn r50154).

The upstream reproducer, however, does not crash webkitgtk or qt.
Comment 4 Rex Dieter 2014-09-23 14:17:12 UTC 
Confirmed this is fixed in el6's qtwebkit-2.1.1 and fedora's qtwebkit-2.3.x
Comment 5 Rex Dieter 2014-09-23 14:17:28 UTC 
make that epel-6's qtwebkit-2.1.1
