On the Ubuntu bug about this, I found a reference to the freedesktop
spec[1] which suggests these should probably be x-scheme-handler/foo
instead.

Checking lxr, usage is:
* matching oxygen-icons eg. /22x22/mimetypes/uri-mmst.png (and a script
in calligra that checks against oxygen-icons)
* kplayer
* kio/src/ioslaves/protocols/foo.protocol
* kde-dev-scripts list of what appears to be mime types renamed kde 3 -> 4
* Some old emerge stuff

So, can we just change the kio .protocol files and document that on the
porting notes?
