Bug 452819

Works for me. What happens if you use `xdg-open` instead?

I tested it, I got the same result :-(.
I do not know, why this is happening. Theoretically, if I remember well, I did not change anything in my OS settings.
I have another PC running the same OS (Manjaro with KDE) and there I don't have this problem.

Sounds like the MIME type data on your system has gotten messed up, if xdg-open does it too. That means no KDE code is involved, so that part of the issue isn't a KDE problem.

Can you run `file --mime-type <path/to/a/file>` and tell me what it says?

And can you attach ~/.config/mimeapps.list?

Maybe, I do not know :-(.

$ file --mime-type ~/Downloads/account.move.csv
Letöltések/account.move.csv: text/plain

$ cat ~/.config/mimeapps.list

Can you remove the two `x-scheme-handler/file=org.kde.dolphin.desktop;` lines and see if that fixes it?

ahh, yeee, finally, it works normally!!!!
Thx, Nate, very much!!!

Looks like your config file had some corrupt entries in it, yeah. We don't add those so I don't think it's a KDE bug.

I don't know which application(?) put these lines here. I didn't do it, that's for sure :-)
