Application: digikam (4.12.0)
KDE Platform Version: 4.14.13
Qt Version: 4.8.6
Operating System: Linux 4.2.0-34-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed: This report is related to report 361310. I used the kipi plugin for merging pics from an exposure series. This time I skipped the enlignment because it crashes anyway (see 361310) but when the assistant came to using enfuse digiKam crashed.

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