Dolphin and ftp

I’m witnessing some weird ftp behaviour.

  • If I right click in an ftp folder and create a file. the file is created

  • If I right click on this file and select delete it is deleted

  • If I copy paste a file I get a “Access denied” error

  • If I open a terminal I see the local mount /run/user/1000/kio-fuse-xxxx folder and if I create a folder there (mkdir weird) I get an error “mkdir: cannot create directory ‘weird’: File exists” although there is no folder nor file “weird”

  • If in that same terminal I type echo hallo > hallo.txt a file hallo.txt is created with exactly that contents

Is dolphin acting funny with ftp servers?

Looks like https://bugs.kde.org/show_bug.cgi?id=394649

What do the permissions look like for the ftp folder?
