SFTP Not Working On The Fedora 21 KDE Spin?

Attempting to connect to SFTP from Dolphin gave an Error.  Which made no sense, as I knew the remote port was open, and I could connect via the command line SSH.  I am using the KDE Plasma Desktop Spin for Fedora 21.

If you are getting this, its an easy fix - some library was missing and I'm not sure which (writing this after the fact).  But the KDE Spin didn't have the full KDE group installed, so just do:

sudo yum groupinstall "KDE Plasma Workspaces"

Now try connecting.
