           Summary: [Gtk] Plugin Load crashes with NP_FULL mode
           Product: WebKit
           Version: 526+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Plug-ins
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: sriram.neelakandan at gmail.com


NP_EMBED mode plugin works fine,
when the same plugin is loaded with the URL, it crashes at 


void PluginView::didReceiveData(const char* data, int length)
{
    ASSERT(m_loadManually);
    ASSERT(m_manualStream);
    m_manualStream->didReceiveData(0, data, length);
}

On further DEBUG i found m_manualStream is NULL.

Reason: PluginView::didReceiveResponse does not get called, from
FrameLoaderClient::commitedLoad.

FrameLoaderCleint::m_hasSentResponseToPlugin is not initialized and has some
JUNK data. So the following check fails :
        if (!m_hasSentResponseToPlugin) {
            m_pluginView->didReceiveResponse(loader->response());
            m_hasSentResponseToPlugin = true;
        }

I will attach a patch shortly to initialize m_hasSentResponseToPlugin
