Application: dngconverter (4.12.0)
KDE Platform Version: 4.14.16
Qt Version: 4.8.7
Operating System: Linux 4.4.0-22-generic x86_64
Distribution: Ubuntu 16.04 LTS

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

In each case I have launched dngconverter from the command line with a single file as the argument. The file appears to load correctly, and then I press the "Convert" button. At that moment the application crashes.

I have experienced this on a CR2 file from a Cannon 50D, an ARW from from a Sony NEX-7, and an ARW file from a Sony A-6000.

The crash can be reproduced every time.

-- Backtrace:
