Application: digikam5 (5.3.0)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-47-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

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

I opened digikam5 from the commandline. (Opening in other ways also crashes).

digikam5 was installed form Philip Johnsson's PPA.

Below is the commandline output:
