New crash information added by DrKonqi

digikam (2.1.1) on KDE Platform 4.8.2 (4.8.2) using Qt 4.8.1

- What I was doing when the application crashed:
I tried to send 2 selected pictures by email (Kmail). Clicking on OK will crash digicam every time.

Problem is not reproducible with new Send by Mail tool from digiKam core introduced with digiKam 5.7.0. The tool is available everywhere : Image Editor, Album View, Showfoto and Light Table. The items to send by mail can be selected by icon view items selection or by albums selection.
