Application: digikam (3.5.0)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.13.0-51-generic x86_64
Distribution: Ubuntu 14.04.5 LTS

-- Information about the crash:
- What I was doing when the application crashed:

I opened the Import dialogue, PTP, kept my default import settings and selected Download All. The Import started. Then I moved my mouse to top left screen corner to switch windows/desktop (I'm on Ubuntu 14.04 with Gnome shell).  After that digiKam crashed. Some of the photos have been downloaded before the crash. 

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