I can reproduced it on 32 bit too:

#0  0xf676a9c8 in WebCore::InspectorFrontendClientQt::inspectorClientDestroyed (this=0xffffffff) at ../../../WebKit/qt/WebCoreSupport/InspectorClientQt.cpp:351
351         m_inspectorClient = 0;
(gdb) bt

It seems m_frontendClient is invalid for some reason. (this=0xffffffff)

void InspectorClientQt::inspectorDestroyed()
{
    if (m_frontendClient)
        m_frontendClient->inspectorClientDestroyed(); 
        ---> crash!!! (InspectorClientQt.cpp:104)
    delete this;
}
