Created attachment 53019 [details] Patch that solves issue. Version: unspecified (using Devel) OS: All OpenRaster, a file format used by Krita and others, uses ODF compatible thumbnails. Thus kofficethumbnail will be able to give previews for this file-format if the appropriate entry is added to the .desktop file. This will improve usability for users of this file format by giving them previews in Dolphin and other KDE applications. Reproducible: Always
Thanks!
