           Summary: [Qt] qtwebkit 2.3 crashes upon closing a onmouseover
                    alert (may need several tries)
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
               URL: http://oserv.org/bugs/qtwebkit-crash/2.3.html
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Critical
          Priority: P2
         Component: WebKit Qt
        AssignedTo: webkit-unassigned at lists.webkit.org

The testcase v2.3.

See http://oserv.org/bugs/qtwebkit-crash/2.3.html, http://oserv.org/bugs/qtwebkit-crash/2.2.html, http://oserv.org/bugs/qtwebkit-crash/2.1.html (that's not qtwebkit version numbers, that's the testcase version numbers).

It crashes konqueror+kwebkitpart, adiumthemeview, rekonq on closing a first-second alert (for the 2.3.html testcase).
Arora and designer-qt4 + qwebview + ctrl-r needs a little more tries for me, but then it hangs and consumes large amount of memory before finally crashing.

Does not seem to happen in Qt5 for me.

Have not tested qtwebkit versions prior to 2.3.
