I'm trying to use kompare, but when I go to save the file, I'm told that it could not be save. I see

couldn't create slave: "Unable to create io-slave:\nklauncher said: Unknown protocol 'file'.\n"

in the stderr, and Googling for this problem seems to always be solved by installing kio. But I have installed kio.

Originally, I was getting another error to the stderr, so I followed the instructions at Problem with KDE programs after upgrading to 15.04. That corrected some of the error messages, but this one lingers.

I'm running Ubuntu 16.04 64-bit and XFCE


Looks like another little thing I needed was pkill kdeinit. That cause klauncher to restart.
