is this enough?

Strange. It look like an indeep crash in Qt4... Which version you use ?

Gilles Caulier

libqt 4.6.0-77.2.x86_64
digikam 1.0.0-21.12-x64_64

from: http://download.opensuse.org/repositories/KDE:/KDE4:/Factory:/Desktop/openSUSE_11.2/x86_64/

Same crash as 219512.
Can you also confirm that switching that "Window theme to anything else then Oxygen" - I guess meaning the style - fixes the problem?

now it works fine with rc1
