Description Denis 2024-04-08 10:45:01 UTC

After update to Plasma 6, krusader internal viewer lost its ability to recognize mime-types. It does not highlight text inline with file extension, when attempting to open image file it opens ASCII-text instead… when running from command line there is the warning output: kf.service.services unknown@0 # KMimeTypeTrader: MIME type “all/allfiles” not found. Purging/Reinstalling krusader did not solve the problem. on plasma 5 all worked fine. 
made a post on it: https://discuss.kde.org/t/krusader-issue-with-mime-types-after-p6-update/13712

STEPS TO REPRODUCE
1. install latest kdeneon userediton
2. install latest krusader (2.8.1)
3. open krusader
4. try to open .xml, .cpp, ... or try to open any image file .png, .jpeg, ... with internal viewer (press F3)
5. behold

OBSERVED RESULT
in case of text file - it is plain text (no highlighting)
in case of image file - it is ASCII code (no image)

EXPECTED RESULT
in case of text file it should be highlighted text
in case of image file it should be image

Comment 2 Denis 2024-04-21 17:06:36 UTC

Hallelujah, i found that it has something to do with libkf5khtml-bin package, once it is installed Internal Editor starts to open images (with F3) !!  But unfortunately there is no image scaling button... see my last comment at https://discuss.kde.org/t/krusader-issue-with-mime-types-after-p6-update/13712

Comment 5 Alex Bikadorov 2024-07-15 13:56:28 UTC

I could not reproduce this but assume that it will be fixed when Krusader is ported to KF6.

Comment 6 Alex Bikadorov 2024-09-25 14:44:17 UTC

Fixed in current master (Krusader was ported to KF6.)
