I'm getting a crash in c:\qt\4.7.1\src\3rdparty\webkit\webcore\platform\text\qt\textbreakiteratorqt.cpp line 59
Qt version 4.7.1
the iterator.string is invalid.
TextBreakIterator* setUpIterator(TextBreakIterator& iterator, QTextBoundaryFinder::BoundaryType type, const UChar* string, int length)
{
if (!string || !length)
return 0;
if (iterator.isValid() && type == iterator.type() && length == iterator.length
&& memcmp(string, iterator.string, length) == 0) { -<--------crash
iterator.toStart();
