I did not update any packages during these days. But a few days ago, I lost about five pictures (out of 300) on the same system. It is strange, but since I know of this bug and having turned on debug output, no further image got destroyed. Additionally there is a temporary file of 61 with digikams PID as suffix leftover.Īnd here is another gentoo linux user confirming this problem: 63 has zero size, 64 is now about 75% larger than before (concatenated data of 63?). For example I rotated 6 pictures at the same time (58, 60, 61, 62, 63, 64), 60 and 61 were reported as failed, but 58, 60, 61 and 62 have been rotated, 63 and 64 have been destroyed. ![]() Interestingly not the pictures being reported as "JPEG transform failed" but others are destroyed. Rotating larger amounts of images at the same time seems to make the problem worse, as until now I could not reproduce the error while rotating single files. I'm rotating groups of selected pictures via shortcut and images get destroyed in various ways as described above (size 0, reduced or even increased). Using a similar configuration as Reinhard Biegel I'm also on Gentoo x86_64 with digikam-3.1.0, images on ext4 FS, but libjpeg-turbo-1.2.1 and experiencing similar problems. Not really news, but just to push the really critical bug (backup of raw images is essential, otherwise data loss occurs) to a "confirmed" status:
