Application: dngconverter (4.12.0)
KDE Platform Version: 4.14.16
Qt Version: 4.8.7
Operating System: Linux 4.4.0-13-generic x86_64
Distribution: Ubuntu Xenial Xerus (development branch)

-- Information about the crash:
- What I was doing when the application crashed: I added a canon cr2 file. Lossless compression was ticked, Jpeg Preview was set to mediium and I instructed the app to store as a different name. When I clicked on Convert the app crashed.

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