IIRC I tried InitialPreference=10 but to no effect (but then we all fail sometimes). But I did not inspect preferredService(), just looked at the name it seems :) So the sorting by preference is already done when creating the cache I learn by your comment? For KDELIBS NG I wonder if a thumbnail control should be added to the File Association settings, so the user can control which plugin stamps the thumbnail, if any. At least Calligra 2.6 will signal support for quite a lot of file types (due to the filter system there can be many), so overlapping of thumbnailers might happen more often. - Friedrich W.
