Application: digikam (5.5.0)
 (Compiled from sources)
Qt Version: 5.6.2
Frameworks Version: 5.34.0
Operating System: Linux 4.11.7-ck x86_64
Distribution (Platform): Gentoo Packages

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

I started freshly digikam, created an album and tried to fill it up. So I clicked the Import button (with the camera icon), then I realized it is not what I wanted so I tried to close the window. It didn't work so I had to kill it with xkill.

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