--- Comment #5 from tagwer...@innerjoin.org --- There's a section covering detecting modifications: https://specifications.freedesktop.org/thumbnail-spec/thumbnail-spec-latest.html#MODIFICATIONS If I delete all the thumbnail PNGs, touch one of the source images and rerun the test, the thumbnails work as they should. If dolphin is checking the filename and modification time, that's not enough for my case. It also proved not enough for the test scenario (which is of course simplified!). Add in a check of the file size, and it would have been OK. -- You are receiving this mail because: You are watching all bug changes.
