           Summary: Crash on KHTMLPart inside kontact. Possibly related to
                    Qt cursor handling.
           Product: kontact
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: rasasi78 at gmail.com

Application that crashed: kontact
Version of the application: 4.3.0
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-toi3 x86_64
Distribution: Debian GNU/Linux unstable (sid)

What I was doing when the application crashed:
I opened an url pointing to a picture from the akregator component of kontact.,
I went back and forth using kontact arrows in the toolbar. I could see the
picture several times, but when I asked kontact to go back, forth or move the
image using key arrows (can't remember which of the 3 I did), kontact crashed
as detailed below.

I've see other bugs possibly due to the same problem, which could be in Qt.
Those bugs are: https://bugs.kde.org/show_bug.cgi?id=199907 and
https://bugs.kde.org/show_bug.cgi?id=196512

I'm on Debian sid (Linux 2.6.30), KDE 4.3 and Qt 4.5.2.

Regards,
