           Summary: [Qt] "dangling" pointer to qwebpage's view object can
                    leads QGLauncher to crash
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: All
            Status: NEW
          Keywords: Qt
          Severity: Normal
          Priority: P2
         Component: WebKit Qt
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: tonikitoo at webkit.org

backtrace 1

Steps to reproduce:

1) Open QGLauncher
2) Go to File->Clone View
   (a 'cloned' view shows up)
3) Put focus on the first window and load a valid URL
   (problem better reproducible w/ sites that take a while to complete the load
and require theming, e.g. a search on google.com)
4) While it is loading, move mouse over the second window and do some random
movements (mouse hover)
5) and yet while it is loading, close the second window.

QGLauncher crashes while accessing qwebpage::view(), which holds a "dangling"
pointer.
