--- Comment #7 from Maik Qualmann <metzping...@gmail.com> --- No, even if digiKam is busy the behavior can not arise. I have special images that cause the behavior for testing purposes. The video thumbnailer is the last attempt, he would also create a thumbnail with JPG, with filmstrip. I think that your images can not be read temporarily and are even broken in the disk cache. Normally I can not reproduce this behavior, not even on my relatively slow router NAS (FritzBox with a large USB stick). Maik -- You are receiving this mail because: You are watching all bug changes.
