Application: digikam (4.0.0)
KDE Platform Version: 4.13.0
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic x86_64
Distribution: Ubuntu 14.04 LTS

-- Information about the crash:
- What I was doing when the application crashed: I drag selected the majority of images on the camera, 64 out of 68, then chose the "download and delete selected" option for the import. On making that menu selection the application crashed immediately. It has done this before in the same circumstances.

The crash can be reproduced sometimes.

-- Backtrace:
