digikam and kipi-plugins?

[Per Bothner <per bothner com>]

The Rawhide version of digikam is the very latest (0.10.0-rc1),
but it fails to find any of the "Kipi plugins", even though I've
installed the kipi-plugins package.  This might be an upstream
issue, since 0.10.0 is pretty bleeding edge and the kipi-plugins
may even more bleeding-edge.  Gwenview does seem to be see the
plugins, so I'm wondering if there is there might be a
Fedora-specific problem before I complain upstream ...
