Sentry Crash Report:

Description savanni.dgerinel 2016-05-17 05:28:35 UTC 
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:
Application: DNG Image Converter (dngconverter), signal: Segmentation fault

Whether this is a duplicate of another bug or not, the bug is not resolved. My system has all of the processing files from the Oxygen theme installed in the correct place:

This has been going on for months, including many library upgrades, system upgrades, and reboots. I see no resolution in any of the supposed duplicates.

Copy the icon in your home directory. See here:

Comment 4 savanni.dgerinel 2016-05-19 04:52:58 UTC 
Odd. That solves the problem if I launch DNGConverter from Digikam. If I launch it from the command line, the crash persists. However, my 99% use case is to launch DNGConverter from Digikam, so I am satisfied with this as a workaround.
Comment 5 caulier.gilles 2016-06-30 13:00:13 UTC 
Problem still reproducible using last digiKam 5.0.0-beta7 ?

Comment 6 caulier.gilles 2016-07-02 16:03:56 UTC 
This tool have been moved to digiKam core. Problem is not reproducible.
