Description Jocelyn Turcotte 2009-11-19 04:36:24 PST
If we have a QWebPage that created its own QWebInspector, it will delete it in destructor of QWebPage.
The problem is that its deleted in QWebPagePrivate::setInspector, itself called by QWebPage::d->inspector->setPage(0).
When setPage resumes, it tries to access its memory which can lead to a crash.

Other Qt tests have a section in the .pro file specific to symbian that looks like:
symbian {
    TARGET.UID3 = 0xA000E540
    TARGET.CAPABILITY = ReadUserData WriteUserData NetworkServices

I'm not sure about what to put in the UID3 field so I omitted it from the patch.
Please tell me if you have an idea.
