Application: digikam (6.2.0)
 (Compiled from sources)
Qt Version: 5.9.8
Frameworks Version: 5.60.0
Operating System: Linux 4.14.23-ck1-mainline-core2-rjvb x86_64
Distribution: Ubuntu 14.04.6 LTS

-- Information about the crash:
- What I was doing when the application crashed:
1) imported photos from a GPhotos album into a new digiKam album on a local disk
2) hit the "Start ..." button once more to see if the download process is clever (it isn't, it started importing photo 0 from the 53 in the album)
3) closed the wizard after 2 or 3 imports

DigiKam crashed immediately.

The "this" pointer in the top few functions in the backtrace looks suspect, a stale or otherwise non-initialised member variable?

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