[Qt-qml] S60 WebView

[Jack Wootton]

OK, so it's this bug that was causing my problem.  Thank you for linking to
it.

I could have saved myself two weeks of pain had I searched the bugs database
immediately after having a problem rather than attempting to find a problem
myself :P Definitely didn't help myself there.

Lastly, I don't want to appear difficult, since I really do have almost
nothing but praise for Qt and QML, it simply is a massive undertaking and is
looking really, really good.  But.  Wasn't WebView at least tested on one
S60 device before releasing a binary?

Kind regards,
Jack
