Sentry Crash Report:

Description Pierre Zweigenbaum 2010-03-29 23:25:31 UTC

Application that crashed: digikam
Version of the application: 1.1.0
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.12-desktop-3mnb x86_64
Distribution: "Mandriva Linux 2010.0"

What I was doing when the application crashed:
I was dragging an image from Digikam to the Kmail e-mail editor where I had started writing a message.
Since KMail was in a different desktop than digikam, I used the Ctrl-tab keyboard shortcut to switch desktops while still holding the dragged image. At that point Digikam crashed.
(note that I have succeeded in dragging and dropping files and digikam images across desktops, including to the same message shortly before the crash)

I recommend to test again with last digiKam 1.2.0, released yesterday...

digiKam and Kipi-plugins 1.2.0 are out. Please check if crash is still valid there.

Thanks in advance

This crash is located deep inside Qt drag handling. I doubt we can fix anything.
