Segfault to do with QUrl

Hi there,

I have build PhantomJS (https://github.com/ariya/phantomjs) against Qt 4.8, and I am experiencing segfaults. The stack traces are not always the same, but they can be seen here: https://gist.github.com/1430393

I have spoken to the developer of PhantomJS and he says it points to a memory bug in QUrl.

Please let me know if I can assist any further in solving this issue, though I'm afraid C++ is not my area of expertise so there's a limit to what I can do!

Thanks
