If gphoto debug logs are needed, I can provide ones against working 2.5.16 and non-working, but they are rather large (about 100M uncompressed each, 75M both tar+xz'd). I think the problem is that you are using gphoto2 version 2.5.16 with libgphoto2 version 2.5.17. There is a gphoto2 version 2.5.17. I forgot to upload it. :(. I am really sorry about that. I am starting to do the pachage now. Sorry to bring bad news, but I now tested gphoto2 from GIT (with GIT libgphoto2) as well, and the problem persists with that. :( -- [ ..
