Application: digikam (2.6.0)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-3-amd64 x86_64
Distribution: Debian GNU/Linux testing (wheezy)

-- Information about the crash:
- What I was doing when the application crashed:
export to picasaweb 1 image.
This image was previously exported to the same album. Normaly in that case, I have a dialog window that request me if I want to overwrite the previous uploaded image. But digikam crashed.
Since the first export, I fliped the image (rotate 90 degrees).
The first export consisted in album creation, and export of 35 images.

I retried once : same problem.

The crash can be reproduced every time.

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