While accessing an older collection on a removable drive, digikam (Linux x64 appimage 5.3.0 on Ubuntu 16.04 LTS) eventually segfaults (on the same image, which is 64 MB big, and can be found for the next few weeks on http://srv.cornils.net/DSC09641-hdr.dng): digikam.dimg: "/media/mcornils/82aad9c3-7dc9-4db0-9616-177ee44af6c7/fotos/2012-09-01 Nepal: Tatopani, Dhulikhel, Bakthapur, Kathmandu, Patan, Langtang/hdrenblend/DSC09641-hdr.dng" : RAW file identified digikam.rawengine: LibRaw: failed to run open_file: Unsupported file format or not RAW file digikam.dimg: "/media/mcornils/82aad9c3-7dc9-4db0-9616-177ee44af6c7/fotos/2012-09-01 Nepal: Tatopani, Dhulikhel, Bakthapur, Kathmandu, Patan, Langtang/hdrenblend/DSC09641-hdr.dng" : QIMAGE file identified TIFFReadDirectory: Warning, foo: unknown field with tag 18246 (0x4746) encountered.

Yes, this crash is not reproducible here with 5.4.0 pre release AppImage. This bundle use now Libraw 0.18 beta2. So this problem will be fixed with next 5.4.0... Gilles Caulier
