Application: dngconverter (4.12.0)
KDE Platform Version: 4.14.16
Qt Version: 4.8.7
Operating System: Linux 4.4.0-83-generic x86_64
Distribution: Ubuntu 16.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:  The RAW image is a .RW2 file from a Panasonic Lumix ZS-60 that I had copied to my hard drive. When I clicked on the RAW file, DNG came up, showing the correct thumbnail.  I left the app at its default settings and clicked the CONVERT button, and it crashed.

The crash can be reproduced every time.

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