--- Comment #5 from MILAS Robin <milas.ro...@live.fr> --- Ok so I finally found the cause. This is due to KFileItemModel using setDelayedMimeTypes(true) on its KDirListener. This means that the mimetype is determined by file extension EXCEPT when item are sorted by types. Meaning that my preview does not work when files are sorted by names, but does display when files are sorted by types !! I'm gonna take a look a bit latter to try to see where this can be fix. There still be some other strange behaviour, which I think might be due to more time to execute full mime research on files when in a big folder because for a strange reason the preview and mimetype does work in my download folder without being sorted by types -- You are receiving this mail because: You are watching all bug changes.
