When I call "kfmclient openProfile websites", where "websites" is a profile that I've been using for many years, I get a popup message that says: "Unable to create io-slave. klauncher said: Unknown protocol 'error'." It also pops up an error message within konqueror that says: "The file error:/?error=105&errText= could not be loaded, as it was not possible to read from it. Check if you have read access to this file."
I just upgraded to Kubuntu 17.10, and I noticed that Konqueror's Profiles menu is gone. This is killer feature for me, so I was shocked to see it missing. Please tell me that this wasn't intentional.
