kpasswdserver broken on 19.09

florianjacob commented 4 years ago

Describe the bug As of 19.09, dolphin can't connect to smb network drives becasue kpasswdserver is unable to start up but chrashes kiod5.

To Reproduce Steps to reproduce the behavior:

Open dolphin
Enter smb://live.sysinternals.com/ in the address bar, or any other smb share in your network
Dolphin displays a timeout or access denied, check journalctl -rb for the actual error

Expected behavior Dolphin shows the smb share's content, using stored passwords if available.

Screenshots journalctl -rb:

Additional context I guess this is caused by https://github.com/NixOS/nixpkgs/issues/65399 but I don't know enough about where kpasswdserver actually lives and comes from to fix this myself.

This does not only happen when trying to connect to samba shares, in my case this issue is triggered by the baloo_file_extractor indexer running in background, frequently causing kiod5 to dump core.

We need to wrap libexec/kf5/kiod5 in kio.

schmittlauch commented 4 years ago

@ttuegel What exactly needs to be wrapped there?

NixOS / nixpkgs
