Hi!

The patch I sent tonight hinders kdesktop to even try to delete
devices:/ items, but still if an application tries KIO::del("devices:/cdrom")
it will get deleted.

The attached patch checks in CopyJob and DeleteJob if the protocol
supports deleting and doesn't even stat then. The problem is that
devices:/ (and lan:/ from what I heard) redirect URLs to protocols
that _can_ delete, so if you delete these meta URLs you end up
deleting something real - and this is at least confusing (and as this
dangerous)

Greetings, Stephan
