Bug 484220

SUMMARY

I have entries like below to ~/.ssh/config (the below is just an example, I do have other hosts configured to use specific ssh keys)

```
Host some_local_host
  User redacted
  HostName 192.168.1.23
  Port 22
```

When I open dolphin and try to access `sftp://some_local_host` I get an error 
```
Internal Error
Please send a full bug report at https://bugs.kde.org
Could not set host
```
This problem appeared some time ago, I was on Kububtu 22.04 and after an update the functionality broke, before the update it was working fine, I have updated to Kubuntu 23.10 but the functionality is still broken (I do not know what versions I had before on Kubuntu 22.04).


STEPS TO REPRODUCE
1. set custom configuration in ~/.ssh/config
2. try to access sftp for the added hostname

OBSERVED RESULT
Cannot connect to host, got below error

Internal Error
Please send a full bug report at https://bugs.kde.org
Could not set host


EXPECTED RESULT
Ask for password if necessary and connect to host using sftp.
