Resetting the product to the kio-extras as the jpg thumbnailer is part of the kio-extras. The KDE is following the Freedesktop standards and specifications. There is Thumbnail Managing Standard: https://specifications.freedesktop.org/thumbnail-spec/thumbnail-spec-latest.html . The standard has 'Thumbnail Creation Failures': https://specifications.freedesktop.org/thumbnail-spec/thumbnail-spec-latest.html#FAILURES. I'm not sure if the KDE has implement it ? To redo the thumbnails the user can clean the thumbnail cache: - Gwenview has this in the advanced settings. - Sweeper ( https://www.kde.org/applications/utilities/sweeper/ ) has this option - needs Git commit 9c9586579f6f0dc7c0db73cf7683e94ab61526d7 - https://bugs.kde.org/show_bug.cgi?id=361482#c12 There is also an option to make a servicemenu to remove single thumbnails. -- You are receiving this mail because: You are watching all bug changes.
