           Summary: Crash with "-graphicssystem raster"
           Product: digikam
           Version: 2.0.0
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: christoph at maxiom.de


Application: digikam (2.0.0)
KDE Platform Version: 4.7.40 (4.7.40 (KDE 4.8 >= 200110623) (Compiled from
sources)
Qt Version: 4.7.4
Operating System: Linux 2.6.37.6-0.5-desktop i686
Distribution: "openSUSE 11.4 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:

I am pretty sure this is a Qt bug, but maybe you can reduce it to a minimal
test case to attach to a Qt bug report.

The crash happens when I hover the small "Prev/Next/Rotate/etc." icons when
they partially overlap the image in the simple builtin image viewer.

When running with "-graphicssystem native" that crash does not happen.

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
