On restarting my computer, the unusually-named tmp directory was as you might expect no longer there.
On restarting k3b the unusually-named tmp directory returned. It had the same format, with the same apparently random characters: /tmp/kde-<username><5-random-characters>.
The contents of this directory, I forgot to mention before: a file called xauth-1000-_0
Again, problem solved by creating a tmp directory: /tmp/kde-<username>
The upshot of this problem is that k3b will never work out of the box for me. I will always have to create a tmp directory before I can get it to burn a disc.
