<pre>This problem is fixed in digiKam-5.8.0. The thread support for libraw was not
activated, it only affects NEF files.

<pre>Gilles,
My system has a 6 core CPU with 16 GB of main memory; OS is openSUSE
Leap 42.3, I am running DK 5.7.0-178.7 as provided by SUSE distribution.
I am encountering a problem with multi core processing in BQM when
converting NIKON raw files and using all 6 cores; BQM is using the
following workflow:
Color Auto-correction
Sharpen Image
Color Effects
Convert to JPEG
This works fine with just ONE image in the run-Queue and "Work on all
processor cores" enabled. With more than one image in the queue I only
get a pattern of fine lines in RGB colors in the resulting jpegs .
Disabling "Work on all processor cores" I get correct results for all
pictures, but clearly at the prize of loosing all the possible speedup
of the 6 cores.
With all cores enabled I can see that every core is allocating its one
memory, and there is definitely enough memory on my system.
Could it be, that for some reason the memory gets mixed up among the six
running jobs? Or am I doing something wrong?
Best regards,
Robert Zeller
