           Summary: consistent crash when webView is disposed in response
                    to navigating to a dragged link
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: grant_gayed at ca.ibm.com

- happens with the GTK+ 3 and GTK+ 2 ports
- affects Eclipse's use of WebKitGTK

Steps:

1. Add GtkLauncher's main.c:

static int navigationPolicyCb(WebKitWebView* web_view, WebKitWebFrame* frame, WebKitNetworkRequest* request, WebKitWebNavigationAction navigation_action, WebKitWebPolicyDecision* policy_decision) {
    static int counter = 0;
    if (counter++ > 0) {
        gtk_widget_destroy (GTK_WIDGET(web_view));
    }
    return 0;
}

2. Add to main.c's createBrowser() implementation:

g_signal_connect(webView, "navigation-policy-decision-requested", G_CALLBACK(navigationPolicyCb), window);

3. Create an .html file with:

<HTML>
<BODY>
<A href="http://asdf">drag me out then back in</A>
</BODY>
</HTML>

4. Launch GtkLauncher and pass the created .html file's path (eg.- "./GtkLauncher file:///opt/welcome.html").
5. In the launched window drag its contained link outside of the window and then back in, then mouse up.
6. Leads to a crash in the event loop: _ZL24webkit_web_view_drag_endP10_GtkWidgetP15_GdkDragContext.
