Assertion failure in WebInspectorProxy::platformClose closing main window when inspecting a popup window, or when running regression tests.


>    WebKit.dll!WebKit::WebInspectorProxy::platformClose()  Line 174 + 0x25 bytes    C++
    WebKit.dll!WebKit::WebInspectorProxy::invalidate()  Line 74    C++
    WebKit.dll!WebKit::WebPageProxy::close()  Line 240    C++
    WebKit.dll!WKPageClose(const OpaqueWKPage * pageRef=0x061f0f58)  Line 103    C++

ASSERT(m_inspectorWindow) is the failing assertion.

To get rid of the if in Release builds, you could do:

ASSERT(!m_isVisible || m_inspectorWindow);
ASSERT(!m_isVisible || m_inspectorView);

> Source/WebKit2/UIProcess/win/WebInspectorProxyWin.cpp:181

Have you verified that this is true even when the inspector is docked?

We don't support a docked inspector in WebKit2 yet, but I will make sure to check this when we do.

Thanks!
