Hello again. I reply to myself.
I tried with the same files on another hardware but similar install of Darktable 1.6.7 on Ubuntu 14.04.2 LTS: I get the same errors. So, - either I do something wrong in the process (I still don't know if I need to export some files or leave only the raw files in the folder where the script runs) - or there is something wrong in my install, but what? Regarding the remarks I made in my initial post, the lack of memory has nothing to do with the problem: I get the same error with memory available in / partition. Would somebody be interested (and kind enough) to try the denoise profiling with these LX100 files? http://demo2.ovh.net/fr/9de4136b1627f6c8472594a7094ee7af/ Thanks very much denis De: "Denis Testemale" <de...@testemale.name> À: "darktable-users" <darktable-users@lists.sourceforge.net> Envoyé: Mardi 21 Juillet 2015 09:39:41 Objet: Segmentation fault when trying to profile denoise Hello DT users, Ubuntu 14.04.2 LTS Darktable 1.6.7 from release PPA ( pmjdebruijn/darktable-release ) I just bought a Panasonic LX100. There's no denoise profiles: I can cheat DT and say it's a GX7 to use GX7's profiles (same sensor, it works well), but I thought it could be a good opportunity to try the denoise profiling myself and somehow contribute a little bit by providing it. The problem is that I can't reach the end of the profiling process and everytime run into a seg fault.
