            Bug ID: 200062
           Summary: Crash in WebContent process with customer schemes
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.
          Assignee: webkit-unassigned at lists.webkit.org

Crash in WebContent process with customer schemes.


WebKit: WebKit::WebURLSchemeTaskProxy::processNextPendingTask() <==
  WebKit: WebKit::WebURLSchemeHandlerProxy::taskDidReceiveData(unsigned long long, unsigned long, unsigned char const*)
    WebKit: WebKit::WebURLSchemeHandlerProxy::taskDidReceiveData(unsigned long long, unsigned long, unsigned char const*)
      WebKit: WebKit::WebPage::urlSchemeTaskDidReceiveData(unsigned long long, unsigned long long, IPC::DataReference const&)
        WebKit: WebKit::WebPage::didReceiveWebPageMessage(IPC::Connection&, IPC::Decoder&)

Everywhere else in WebURLSchemeTaskProxy we protect it with a Ref before later calling processNextPendingTask.
But not in didReceiveData.

So lets do that.
