Application: dngconverter (4.12.0)
KDE Platform Version: 4.14.13
Qt Version: 4.8.6
Operating System: Linux 4.2.0-35-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed:
I clicked on the file, so the default program dngconverter would start. I made no changes except I told it to chose a different file name if the file already exists.
My camera is a Nikon D3300 and it is the first time I am using this program.

The crash can be reproduced every time.

-- Backtrace:
Application: DNG-Bildkonverter (dngconverter), signal: Segmentation fault
