--- Comment #14 from Guenther M. Erhard <guenther-digi...@erhard.mobi> --- In my opinion the problem is the libraw version. Exiv2 is the same version (0.25) on both Ubuntu 14.04 and 16.04. I have now installed libraw 0.16.2 instead of 0.17.1 in my Ubuntu 16.04 and recompiled digikam 4.13 for a test and it is working! After thumbnails recreating they are sharp. So something has changed in libraw 0.17. Guenther -- You are receiving this mail because: You are watching all bug changes.
