           Summary: [GTK] crash when closing video that is streaming
           Product: WebKit
           Version: 526+ (Nightly build)
          Platform: PC
               URL: http://www.youtube.com
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Critical
          Priority: P2
         Component: Plug-ins
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: otte at gnome.org


1) install swfdec-mozilla's plugin from git (I guess Adobe has the same
problem, but didn't test)
2) configure webkit with soup backend (no idea if it'd break with curl, too)
3) go to Youtube
4) watch any video
5) leave site while video is still loading

result:
Program received signal SIGSEGV, Segmentation fault.
