[dolphin] [Bug 457935] Conflict with MIME type and preview
https://bugs.kde.org/show_bug.cgi?id=457935 --- Comment #5 from MILAS Robin --- 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.

https://bugs.kde.org/show_bug.cgi?id=457935 --- Comment #4 from MILAS Robin --- So as far as I am it seems that KCoreDirLister emit items with incorrect mimetype (at least they do not check content, in some case). -- You are receiving this mail because: You are watching all bug changes.

--- Comment #2 from MILAS Robin ---
I don't see the issue content so I will add it back there.
I've got an issue with my custom thumbnailer. I checked it and my thumbnailer
work and even produce thumbnail for the parent folder.
However, the preview of the file is not displayed on the file in question.
The file is a gamecube ISO file. It seems that dolphin use the generic ISO
("raw CD image" MIME:"application/x-cd-image") instead of its dedicated MIME:
"application/x-gamecube-rom".
"xdg-mime query filetype" does correctly report the file as an
"application/x-gamecube-rom".
Dolphin seems to inconsistently use both MIME as the preview work on the parent
folder but not on the file in question as well as proposed programs are the one
for "application/x-cd-image" ignoring totaly the
"application/x-gamecube-rom"associated programs.
